Linux: Queue de travail: crash de kmmcd mmc_rescan avec le noyau Raspbian 4.4.38-v7

1. Overclockez-vous le RPI?
2. Avez-vous essayé une autre carte SD? Je sais que ces cartes bon marché peuvent s'user ou se casser après avoir été utilisées pendant un certain temps. Et ils sont relativement bon marché, donc cela vaut peut-être la peine d'essayer un remplacement.

Je doute que ce soit un problème de firmware. Cela pourrait en fait être une combinaison d'une mauvaise carte et d'un bug dans le pilote. Il se peut que le pilote pense que vous avez retiré la carte même si vous ne l'avez pas fait. Et comme retirer la carte SD pendant que le RPI est en cours d'exécution est un non-non, je pouvais voir pourquoi cela n'avait peut-être pas été bien testé.

Je sais que des efforts sont faits pour remplacer ce pilote par une version en amont. La 4.9 est maintenant considérée comme la version stable du noyau sur le RPI.

1. Non, je n'ai pas changé la vitesse de l'horloge.
2. Il s'agit d'un Samsung MicroSDXC 128 Go EVO Plus UHS-I Grade 1 Class 10 haut de gamme 40 EUR avec deux partitions de 8 Go pour / root et / home.

J'ai complètement testé l'écriture de la carte avec badblocks -w avec les 5 modèles différents avant utilisation et je n'ai trouvé aucun bloc défectueux. Un récent test de lecture badblocks n'a montré aucune erreur non plus. Je suppose que la carte est parfaite.

Je viens de commander un autre Pi 3 et un SanDisk Ultra 64 Go SDXC (80 Mo / Sek) Classe 10 pour exclure les problèmes matériels.

Vous avez manqué l'en-tête de ce noyau, mais un blocage à ce stade ressemble à un symptôme que quelque chose d'autre n'a pas libéré le périphérique MMC, peut-être parce que quelque chose a échoué lors d'une opération précédente. Le pilote sdhost enregistrera les messages d'erreur, donc en l'absence de ceux-ci, je me penche vers le blocage de la boîte aux lettres ARM <-> VPU tout en essayant de configurer l'horloge pour l'interface SD.

De telles erreurs sont souvent le signe d'une alimentation électrique inadéquate. Que signale "vcgencmd get_throttled" sur votre système après une activité typique?

La 4.9 est maintenant considérée comme la version stable du noyau sur le RPI.

Non - c'est toujours la prochaine version jusqu'à ce que nous fassions une version de Raspbian qui l'utilise.

C'est déroutant alors ...

Personnellement, j'aurais d'abord essayé une carte très, très bon marché pour écarter tout problème matériel. Comme le genre que vous obtenez pour 5 $ aux États-Unis. J'en ai en fait rassemblé tout un tas au fil des ans.

Ce que je voulais dire par cartes bon marché, c'est que toutes ces cartes SD sont bon marché. Peu m'importe combien vous les payez, ils sont essentiellement conçus pour le marché des appareils photo / caméscopes / téléphones, de sorte qu'ils ne sont généralement pas abusés de quelque chose qui pourrait bien être allumé tout le temps.

@pelwell Je vois en fait des

J'ai trouvé qu'en particulier en 64 bits, le RPI est instable à 1,2 GHz. La définition du maximum à 1,0 GHz semble aider. Mais je n'ai pas non plus exclu un problème de firmware.

@pelwell De quel en-tête de noyau avez-vous besoin? J'utilise le noyau par défaut de Raspbian 8 Jessie
Linux raspberrypi 4.4.34-v7+ #930 SMP Wed Nov 23 15:20:41 GMT 2016 armv7l GNU/Linux .

Mon alimentation semble stable et suffisante comme conclu à partir de throttled=0x20000 .
J'ai obtenu cette valeur lors d'un test de résistance qui a élevé la température de mon processeur à 80 ° C.

Soit dit en passant, si vous recherchez sur Google kmmcd mmc_rescan vous trouverez également d'autres personnes signalant ce problème.

Pendant ce temps, j'ai remarqué que ce problème est déclenché par le navigateur chrome (Version 51.0.2704.91 Construit sur Ubuntu 14.04, fonctionnant sur Raspbian 8.0) lorsque plusieurs sites sont ouverts.

Veuillez mettre à jour vers le dernier noyau qui peut vous aider, la 4.9 est maintenant la version finale. Veuillez rapporter les résultats.

Malheureusement, je vois toujours le même problème après la mise à niveau.
En attendant, j'utilise:
Linux raspberrypi 4.9.24-v7 + # 993 SMP mer.26 avril 18:01:23 BST 2017 armv7l GNU / Linux
et Chromium Version 56.0.2924.84 Construit sur Ubuntu 14.04, fonctionnant sur Raspbian 8.0

Je n'avais jamais vu cela auparavant, et maintenant je l'ai vu plusieurs fois sous 4.9.80-v7 + lors d'un téléchargement wget très rapide. Je suppose que c'est ce qui a rendu le Raspberry Pi 2 B temporairement insensible, mais il n'a pas planté et le téléchargement n'a pas échoué.

Cela se produit-il toujours sur le dernier noyau 4.14?

Ce problème sera résolu dans les 30 jours, à moins que d'autres interactions ne soient publiées. Si vous souhaitez que ce problème reste ouvert, veuillez ajouter un commentaire. Un problème fermé peut être rouvert sur demande.

malheureusement c'est:

OK, nous devons comprendre ce qui se passe qui pourrait causer cela. Étant donné que cela semble être très rare, y a-t-il quelque chose dans votre configuration qui pourrait être considéré comme un peu inhabituel qui pourrait le promouvoir? Que fais-tu quand ça arrive?

J'ai aussi le même problème, chromium-browser qui "plante" après un certain temps (l'affichage est gelé, mais les journaux du pi suggèrent qu'il était toujours "activé")

Ce qui se passe, c'est qu'à cause de cela, après un certain temps, le pi commence à tuer des tâches et le pi est en quelque sorte dans un état de zombie. C'est un pi utilisé pour l'affichage dans la cafétéria, donc je le redémarre généralement au lieu d'essayer de me connecter via SSH pour voir ce qui se passe. La prochaine fois qu'il plantera, j'essaierai de voir si le système d'exploitation est toujours réactif ou si le pi est vraiment dans une sorte d'état zombie.

Nous pouvons voir que cela "fonctionne" même si l'affichage est figé.

J'ai trouvé une autre chose intéressante:

Les dates ne correspondent pas, mais il y a peut-être quelque chose à creuser ici plus généralement.

Ce qui est bizarre, c'est que j'ai une autre configuration pi exactement de la même manière et que celle-ci ne plante pas. Je vais essayer de vérifier les différences de version, je pense que le hw est un peu différent aussi.

Même chose ici, mais cela n'arrive que depuis que je suis passé de Jessie à Stretch:

«moi aussi», et je peux le reproduire sur deux 3B + différents, avec des cartes SD différentes et des alimentations différentes. Le noyau de stock dans raspbian-stretch-lite 2018-06-27 le fait, 4.14.70-v7 + # 1144 le fait, 4.14.73-v7 + # 1148 le fait.

Il s'agit d'une installation simple, avec ssh activé, et ma charge de travail est assez répétitive: essayez d'user la carte SD. La boucle va:
Écrivez des données aléatoires de 512 octets à des emplacements aléatoires dans un fichier de 2 Mo, un million de fois, en les vidant après chaque écriture.
sync et supprimez les caches.
comparez le contenu du fichier à la «vérité».
utilisez dd pour lire-tester la carte entière.

Parfois, le blocage temporaire est assez long pour que je perde ssh.

J'ai eu l'idée de tester cela sur différents modèles, pour voir si le multicœur ou le wifi était le déclencheur: Non, c'est Pi3 / Pi3B +.

Pi 0W (4pcs): 48 heures d'exécution, pas de panne
J'ai testé 4 cartes (Sandisk A1, SanDisk industrial, NetList SLC, Panasonic Industrial), une dans chaque 0W, avec wifi activé et parlant, pour un total de 192 heures-cartes.

Pi 2 original (1 pc): 48 heures d'exécution, pas de panne
S'il s'agit d'un bogue de verrouillage, il échouerait peut-être sur le Pi2. Il s'agit du premier Pi2, n'utilisant pas le SoC Pi3.

Pi 3 original (1pc): 8 heures d'exécution, 6 échecs, étranglé = 0x0
Il est alimenté par une alimentation 5V 5A vraiment agréable et propre, avec de gros fils courts et un grand dissipateur thermique.

Pi 3B + (3pcs): très variable. Le meilleur a 6 jours d'exécution et un seul échec, le pire échoue une fois par heure en moyenne.

Diverses choses ont essayé:
330uF supplémentaire sur 3.3V. 5V fourni à l'en-tête. Désactiver le wifi. Iperf3 sur wifi lors de la copie. Aucune différence.

Je vois qu'il n'y a pas de mises à jour dans ce numéro depuis un certain temps maintenant ...

J'ai également ce problème depuis que j'ai mis à niveau pour étirer
Matériel: Rpi3

Noyau: Linux raspberrypi 4.14.79-v7+ #1159 SMP Sun Nov 4 17:50:20 GMT 2018 armv7l GNU/Linux

J'exécute plusieurs conteneurs docker, l'un utilise un partage NFS, cela peut-il en être la cause? (transmission)

J'utilise ceci pour le monter:

mount | grep nfs

Depuis quelques semaines, j'ai la même erreur. Mais j'ai un Raspberry Pi 2. J'ai une carte SD Samsung de 32 Go dedans. J'exécute influxdb sur la carte, à côté de Hass, grafana, traefik et Telegraph, le tout dans des conteneurs Docker. Je surveille les stats du raspberry pi, mais je ne vois aucun problème (assez de mémoire, pas de pic de processeur). C'est peut-être parce que trop Mach io sur la carte SD? Après un redémarrage, il fonctionne correctement, même pendant une semaine.

J'ai le même problème depuis quelques mois, chaque nœud de mon Raspberry Pi Kubernetes Cluster a chaque jour (presque toutes les 24 heures) cette exception. En tant que nœuds, j'utilise Raspberry Pi 3 B + et Raspberry Pi 3.

Quiconque est concerné par ce problème peut-il tester ce correctif en amont également disponible dans rpi-5.1.y?

J'ai porté le correctif localement dans la branche 4.19.y et construit le noyau pour tester le correctif. Le système est redémarré et si l'erreur se reproduit, ce sera dans les prochaines 24 à 28 heures ...

@lategoodbye Il semble que le patch ne fonctionne pas, le matin j'ai les mêmes erreurs qu'avant.

@sbiermann Le correctif n'est pas destiné à ce problème. Ce n'était donc qu'un essai.

Ce serait utile pour moi si vous pouviez reproduire ce problème avec mmc / host / bcm2835 (en amont) au lieu de mmc / host / bcm2835-sdhost (en aval). Les deux utilisent le même DT compatible, vous devrez donc modifier la configuration de votre noyau en conséquence (activez MMC_BCM2835 et désactivez MMC_BCM2835_SDHOST).

Merci

@lategoodbye Désolé, je ne suis pas très familier avec la construction d'un noyau, normalement je n'utilise que des images de noyau par défaut ou dans de très rares cas rpi-update donné le noyau. Ces https://www.raspberrypi.org/documentation/linux/kernel/building.md instructions que j'ai suivies pour construire un noyau 4.19.y avec vos modifications des pilotes / dma / bcm2835-dma.c.

Maintenant, j'ai changé mon fichier .config donc je ressemble à:

CONFIG_MMC_BCM2835_MMC = y
CONFIG_MMC_BCM2835_DMA = y
CONFIG_MMC_BCM2835_PIO_DMA_BARRIER = 2
# CONFIG_MMC_BCM2835_SDHOST n'est pas défini

Est-ce exact?

Oui, mais vous devez également avoir (désolé pour les noms déroutants)

CONFIG_MMC_BCM2835 = y

Cela ne fonctionne pas et casse le noyau, le Pi ne démarre jamais. Pour récupérer, j'ai copié l'ancien noyau sur le système et maintenant il redémarre.

J'ai résolu le problème pour moi, mais ce n'est pas une solution générale. Quoi qu'il en soit, je décris ici ma solution de contournement, peut-être que cela aide un autre à résoudre le problème.
Comme il a été écrit précédemment, ma configuration est un cluster kubernetes raspberry pi avec 3 travailleurs et 1 maître. Le maître et 2 du travailleur sont Raspberry Pi 3 B + et un travailleur est un ancien Pi 3 B. Le problème se produit sur chaque travailleur après 24-28 heures lorsque le travailleur exécute mon logiciel de domotique appelé FHEM. Lorsque le problème se produit, Kubernetes a replanifié FHEM pour qu'il s'exécute sur un autre worker, de sorte que chaque worker a le problème. FHEM collecte de nombreuses données à partir de capteurs externes comme la température dans les pièces ou les valeurs des données de chauffage ou de vent. Ces nombreuses données sont écrites via GlusterFS sur un cluster GlusterFS qui est basé sur deux Raspberry 1 avec des clés USB pour les données. Kubernetes et Docker ont écrit leurs messages d'état et d'autres éléments sur la carte SD locale. Ma solution est de redémarrer FHEM tous les soirs à 00h05h00. Après cela, le problème ne se reproduira plus, il est stable depuis le 5 juin. La commande restart arrête le pod kubernetes et kubernetes redémarre le pod après quelques secondes. Cela signifie qu'en arrière-plan, le conteneur Docker dans lequel s'exécute le FHEM sera arrêté et redémarré.
