Linux: Workqueue: kmmcd mmc_rescan stürzt mit dem Raspbian-Kernel 4.4.38-v7 ab

1. Übertakten Sie das RPI?
2. Haben Sie eine andere SD-Karte ausprobiert? Ich weiß, dass diese billigen Karten nach einer Weile abgenutzt sein oder brechen können. Und sie sind relativ billig, so dass es sich lohnen könnte, einen Ersatz zu versuchen.

Ich bezweifle, dass dies ein Firmware-Problem ist. Es könnte tatsächlich eine Kombination aus einer schlechten Karte und einem Fehler im Treiber sein. Es kann durchaus sein, dass der Fahrer denkt, Sie hätten die Karte entfernt, obwohl Sie dies nicht getan haben. Und da das Herausziehen der SD-Karte bei laufendem RPI ein Nein-Nein ist, konnte ich sehen, warum dies möglicherweise nicht gut getestet wurde.

Ich weiß, dass einige Anstrengungen unternommen werden, um diesen Treiber durch eine Upstream-Version zu ersetzen. Auch 4.9 gilt jetzt als stabile Version des Kernels auf dem RPI.

1. Nein, ich habe die Taktrate nicht geändert.
2. Es ist ein High-End 40 Euro Samsung MicroSDXC 128 GB EVO Plus UHS-I Klasse 1 Klasse 10, die zwei 8 GB Partitionen für / root und / home.

Ich habe die Karte mit badblocks -w mit den 5 verschiedenen Mustern vor der Verwendung vollständig schriftlich getestet und keinen einzigen fehlerhaften Block gefunden. Ein kürzlich durchgeführter badblocks Lesetest zeigte ebenfalls keine Fehler. Ich gehe davon aus, dass die Karte perfekt ist.

Ich habe gerade einen weiteren Pi 3 und einen SanDisk Ultra 64 GB SDXC (80 MB / Sek) Klasse 10 bestellt, um Hardwareprobleme auszuschließen.

Sie haben den Header dieses Kernels verpasst, aber ein Stillstand an diesem Punkt scheint ein Symptom dafür zu sein, dass etwas anderes das MMC-Gerät nicht freigegeben hat, möglicherweise weil während eines vorherigen Vorgangs etwas fehlgeschlagen ist. Der sdhost-Treiber protokolliert Fehlermeldungen. Wenn diese nicht vorhanden sind, neige ich zum Blockieren der ARM <-> VPU-Mailbox, während ich versuche, die Uhr für die SD-Schnittstelle zu konfigurieren.

Fehler wie diese sind oft ein Zeichen für eine unzureichende Stromversorgung. Was meldet "vcgencmd get_throttled" nach einer typischen Aktivität auf Ihrem System?

Auch 4.9 gilt jetzt als stabile Version des Kernels auf dem RPI.

Nein - es ist immer noch die nächste Version, bis wir eine Raspbian-Version damit erstellen.

Das ist dann rätselhaft ...

Persönlich hätte ich zuerst eine sehr, sehr billige Karte ausprobiert, um Hardwareprobleme auszuschließen. Wie die Art, die Sie in den USA für 5 US-Dollar bekommen. Ich habe im Laufe der Jahre tatsächlich eine ganze Reihe davon gesammelt.

Was ich mit billigen Karten gemeint habe, ist, dass all diese SD-Karten billig sind. Es ist mir egal, wie viel Sie für sie bezahlen, sie sind im Wesentlichen für den Kamera- / Camcorder- / Telefonmarkt konzipiert, sodass sie normalerweise nicht den Missbrauch von etwas bekommen, das möglicherweise ständig aktiv ist.

@pelwell Ich sehe tatsächlich von Zeit zu Zeit Postfachstillstände und bin mir nicht 100% sicher, ob es sich um das Netzteil handelt, da ich es manchmal sehen kann, selbst wenn das RPI an ein variables Netzteil angeschlossen ist, das 5 Ampere leisten kann.

Ich habe festgestellt, dass der RPI insbesondere bei 64 Bit bei 1,2 GHz instabil ist. Das Einstellen des Maximums auf 1,0 GHz scheint zu helfen. Aber ich habe auch ein Firmware-Problem nicht ausgeschlossen.

@pelwell Welchen Kernel-Header benötigen Sie? Ich verwende den Standard-Raspbian 8 Jessie-Kernel
Linux raspberrypi 4.4.34-v7+ #930 SMP Wed Nov 23 15:20:41 GMT 2016 armv7l GNU/Linux .

Mein Netzteil scheint stabil und ausreichend zu sein, wie aus throttled=0x20000 .
Ich habe diesen Wert während eines Stresstests erhalten, bei dem meine CPU-Temperatur auf 80 ° C erhöht wurde.

Übrigens, wenn Sie nach kmmcd mmc_rescan googeln, werden Sie auch andere Personen finden, die dieses Problem melden.

In der Zwischenzeit habe ich festgestellt, dass dieses Problem vom Chrom-Browser (Version 51.0.2704.91, erstellt unter Ubuntu 14.04, ausgeführt unter Raspbian 8.0) ausgelöst wird, wenn mehrere Websites geöffnet sind.

Bitte aktualisieren Sie auf den neuesten Kernel, der möglicherweise hilft. 4.9 ist jetzt die Release-Version. Bitte melden Sie die Ergebnisse zurück.

Leider sehe ich nach dem Upgrade immer noch das gleiche Problem.
Inzwischen benutze ich:
Linux raspberrypi 4.9.24-v7 + # 993 SMP Mi Apr 26 18:01:23 BST 2017 armv7l GNU / Linux
und Chromium Version 56.0.2924.84 Gebaut unter Ubuntu 14.04 unter Raspbian 8.0

Ich habe das noch nie gesehen und habe es jetzt einige Male gesehen, als 4.9.80-v7 + während eines sehr schnellen Wget-Downloads ausgeführt wurde. Ich denke, dies hat dazu geführt, dass der Raspberry Pi 2 B vorübergehend nicht mehr reagierte, aber er stürzte nicht ab und der Download schlug nicht fehl.

Geschieht dies immer noch auf dem neuesten 4.14-Kernel?

OK, wir müssen herausfinden, was los ist, was dies verursachen könnte. Da dies sehr ungewöhnlich zu sein scheint, gibt es irgendetwas an Ihrem Setup, das als etwas ungewöhnlich angesehen werden könnte, das es fördern könnte? Was machst du, wenn es passiert?

Ich habe auch das gleiche Problem, chromium-browser , das nach einer Weile "abstürzt" (die Anzeige ist eingefroren, aber die Protokolle vom Pi deuten darauf hin, dass es noch "an" war).

Was passiert ist, dass aus diesem Grund nach einer Weile der Pi anfängt, Aufgaben zu töten, und der Pi sich in einem Zombie-Zustand befindet. Dies ist ein Pi, der für die Anzeige in der Cafeteria verwendet wird. Daher starte ich ihn normalerweise neu, anstatt zu versuchen, über SSH eine Verbindung herzustellen, um zu sehen, was los ist. Wenn es das nächste Mal abstürzt, werde ich versuchen zu sehen, ob das Betriebssystem noch reagiert oder ob sich der Pi wirklich in einem Zombie-Zustand befindet.

Der Pi stürzte um Jul 24 17:20 :

Wir können sehen, dass es "funktioniert", obwohl das Display eingefroren ist.

Ich habe eine andere interessante Sache gefunden:

Die Daten stimmen nicht überein, aber vielleicht gibt es hier etwas allgemeineres zu graben.

Was seltsam ist, ist, dass ich ein anderes Pi-Setup genauso habe und dieses nicht abstürzt. Ich werde versuchen, die Versionsunterschiede zu überprüfen. Ich denke, das Hardware ist auch ein bisschen anders.

Das gleiche gilt hier, aber es passiert nur, seit ich von Jessie auf Stretch umgestiegen bin:

"Ich auch", und ich kann es auf zwei verschiedenen 3B + mit verschiedenen SD-Karten und verschiedenen Netzteilen reproduzieren. Der Aktienkern in Raspbian-Stretch-Lite 2018-06-27 macht es, 4.14.70-v7 + # 1144 macht es, 4.14.73-v7 + # 1148 macht es.

Dies ist eine einfache Installation mit aktiviertem ssh, und meine Arbeitslast wiederholt sich ziemlich häufig: Versuchen Sie, die SD-Karte abzunutzen. Die Schleife geht:
Schreiben Sie zufällige 512-Byte-Daten an zufällige Stellen in einer 2-MB-Datei, eine Million Mal, und leeren Sie sie nach jedem Schreibvorgang.
synchronisieren und die Caches löschen.
Vergleichen Sie den Inhalt der Datei mit 'Wahrheit'.
Verwenden Sie dd, um die gesamte Karte zu testen.

Gelegentlich ist der vorübergehende Hang lang genug, dass ich ssh verliere.

Ich hatte die Idee, dies an verschiedenen Modellen zu testen, um festzustellen, ob Multicore oder WLAN der Auslöser war: Nein, es ist Pi3 / Pi3B +.

Pi 0W (4 Stück): 48 Stunden Laufzeit, keine Fehler
Ich habe 4 Karten (Sandisk A1, SanDisk Industrial, NetList SLC, Panasonic Industrial), eine in jeder 0W, mit aktiviertem und sprechendem WLAN für insgesamt 192 Kartenstunden getestet.

Pi 2 Original (1 Stück): 48 Stunden Laufzeit, keine Fehler
Wenn dies ein Sperrfehler ist, würde er möglicherweise auf dem Pi2 fehlschlagen. Dies ist der erste Pi2, der den Pi3-SoC nicht verwendet.

Pi 3 Original (1 Stück): 8 Stunden Laufzeit, 6 Fehler, gedrosselt = 0x0
Dies wird von einer wirklich schönen und sauberen 5V 5A-Versorgung mit kurzen, fetten Drähten und einem großen Kühlkörper gespeist.

Pi 3B + (3 Stück): Sehr variabel. Das Beste hat eine Laufzeit von 6 Tagen und nur einen einzigen Fehler, das Schlimmste fällt durchschnittlich einmal pro Stunde aus.

Verschiedene Dinge versucht:
330uF extra bei 3,3V. 5V an Header geliefert. WLAN deaktivieren. Iperf3 über WLAN beim Kopieren. Kein Unterschied.

Ich sehe, dass es in dieser Ausgabe seit einiger Zeit keine Updates mehr gibt ...

Habe auch dieses Problem, da ich auf Stretch aktualisiert habe
Hardware: Rpi3
OS Raspbian 9.6 (stretch)
Kernel: Linux raspberrypi 4.14.79-v7+ #1159 SMP Sun Nov 4 17:50:20 GMT 2018 armv7l GNU/Linux

Ich verwende mehrere Docker-Container. Einer verwendet eine NFS-Freigabe, die dies möglicherweise verursacht. (Übertragung)

Ich benutze dies, um es zu montieren:

mount | grep nfs
192.168.0.100:/volume1/Downloads on /nas type nfs4 (rw,relatime,vers=4.0,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.0.33,local_lock=none,addr=192.168.0.100)

Gleiche für mich. Das System wurde nach etwa 15 Minuten, in denen es nicht mehr reagierte und die Datei kern.log spammte, wieder betriebsbereit.

Seit ein paar Wochen habe ich den gleichen Fehler. Aber ich habe einen Himbeer-Pi 2. Ich habe eine Samsung 32 GB SD-Karte drin. Ich verwende influxdb auf der Karte neben Hass, grafana, traefik und Telegraph, alle in Docker-Containern. Ich überwache die Statistiken des Himbeer-Pi, sehe aber kein Problem (genügend Speicher, keine CPU-Spitze). Vielleicht liegt es auch an Mach io auf SD-Karte? Nach einem Neustart läuft es auch eine Woche lang einwandfrei.

Ich habe das gleiche Problem seit einigen Monaten. Jeder Knoten meines Raspberry Pi Kubernetes-Clusters hat jeden Tag (fast alle 24 Stunden) diese Ausnahme. Als Knoten benutze ich Raspberry Pi 3 B + und Raspberry Pi 3.

Kann jeder, der von diesem Problem betroffen ist, diesen Upstream- Patch testen, der auch in rpi-5.1.y verfügbar ist?

Ich habe den Patch lokal zurück in den Zweig 4.19.y portiert und den Kernel erstellt, um den Patch zu testen. Das System wird neu gestartet und wenn der Fehler erneut auftritt, wird es in den nächsten 24-28 Stunden sein ...

@lategoodbye Es scheint, dass der Patch nicht funktioniert, am Morgen habe ich die gleichen Fehler wie zuvor.

@sbiermann Der Patch ist nicht für dieses Problem vorgesehen. Es war also nur ein Versuch.

Es wäre hilfreich für mich, wenn Sie dieses Problem mit mmc / host / bcm2835 (Upstream) anstelle von mmc / host / bcm2835-sdhost (Downstream) reproduzieren könnten. Beide verwenden dieselbe DT-Kompatibilität, sodass Sie Ihre Kernelkonfiguration entsprechend ändern müssen (aktivieren Sie MMC_BCM2835 und deaktivieren Sie MMC_BCM2835_SDHOST).

Vielen Dank

@lategoodbye Sorry, ich bin nicht so vertraut mit dem Erstellen eines Kernels, normalerweise verwende ich nur Standard-Kernel-Images oder in sehr wenigen Fällen ein RPI-Update für einen bestimmten Kernel. Diese https://www.raspberrypi.org/documentation/linux/kernel/building.md Anleitung habe ich befolgt, um einen 4.19.y Kernel mit Ihren Änderungen der Treiber / dma / bcm2835-dma.c zu erstellen.

Jetzt habe ich meine .config-Datei so geändert, dass ich so aussehe:

CONFIG_MMC_BCM2835_MMC = y
CONFIG_MMC_BCM2835_DMA = y
CONFIG_MMC_BCM2835_PIO_DMA_BARRIER = 2
# CONFIG_MMC_BCM2835_SDHOST ist nicht festgelegt

Ist das korrekt?

Ja, aber Sie müssen auch haben (Entschuldigung für die verwirrenden Namen)

CONFIG_MMC_BCM2835 = y

Das funktioniert nicht und bricht den Kernel, der Pi bootet nie. Zur Wiederherstellung habe ich den alten Kernel zurück auf das System kopiert und jetzt startet er wieder.

Ich habe das Problem für mich gelöst, aber es ist keine allgemeine Lösung. Wie auch immer, ich beschreibe hier meinen Workarround, vielleicht hilft es einem anderen, das Problem zu lösen.
Wie bereits geschrieben, handelt es sich bei meinem Setup um einen Himbeer-Pi-Kubernetes-Cluster mit 3 Arbeitern und 1 Master. Der Master und 2 des Workers sind Raspberry Pi 3 B + und ein Worker ist ein älterer Pi 3 B. Das Problem tritt bei jedem Worker nach 24 bis 28 Stunden auf, wenn der Worker meine Hausautomationssoftware namens FHEM ausführt. Wenn das Problem auftritt, hat kubernetes FHEM so verschoben, dass es auf einem anderen Worker ausgeführt wird, sodass jeder Worker das Problem hat. FHEM sammelt viele Daten von externen Sensoren wie die Temperatur in Räumen oder Werte aus den Heizungs- oder Winddaten. Diese vielen Daten werden über GlusterFS in einen GlusterFS-Cluster geschrieben, der auf zwei Raspberry 1 mit USB-Sticks für die Daten basiert. Kubernetes und Docker haben ihre Statusmeldungen und andere Dinge auf die lokale SD-Karte geschrieben. Meine Lösung besteht darin, FHEM jeden Abend um 00:05:00 Uhr neu zu starten. Danach tritt das Problem nie wieder auf, es läuft seit dem 5. Juni stabil. Der Befehl restart fährt den kubernetes-Pod herunter und kubernetes startet den Pod nach einigen Sekunden neu. Dies bedeutet, dass im Hintergrund der Docker-Container, in dem das FHEM ausgeführt wird, heruntergefahren und neu gestartet wird.
