Linux: Antrean kerja: kmmcd mmc_rescan crash dengan kernel Raspbian 4.4.38-v7

1. Apakah Anda melakukan overclocking RPI?
2. Sudahkah Anda mencoba kartu SD yang lain? Saya tahu kartu murah ini bisa aus atau rusak setelah digunakan untuk beberapa saat. Dan harganya relatif murah jadi mungkin perlu dicoba penggantinya.

Saya ragu ini adalah masalah firmware. Ini sebenarnya bisa menjadi kombinasi dari kartu buruk ditambah bug di pengemudi. Mungkin pengemudi mengira Anda telah mengeluarkan kartu meskipun Anda belum melakukannya. Dan karena mengeluarkan kartu SD saat RPI sedang berjalan adalah tidak-tidak, saya bisa melihat mengapa itu mungkin belum diuji dengan baik.

Saya tahu beberapa upaya sedang dilakukan untuk mengganti driver ini dengan versi upstream. Juga 4.9 sekarang dianggap sebagai versi stabil dari kernel di RPI.

1. Tidak, saya tidak mengubah kecepatan jam.
2. Ini adalah high end Samsung MicroSDXC 128GB EVO Plus UHS-I Grade 1 Class 10 high end yang dua partisi 8 GB untuk / root dan / home.

Saya telah benar-benar menguji kartu dengan badblocks -w dengan 5 pola berbeda sebelum penggunaan dan tidak menemukan satu blok pun yang buruk. Tes baca badblocks juga tidak menunjukkan kesalahan apa pun. Saya berasumsi bahwa kartunya sempurna.

Saya baru saja memesan Pi 3 lagi dan SanDisk Ultra 64GB SDXC (80 MB / Sek) Kelas 10 untuk mengesampingkan masalah perangkat keras.

Anda melewatkan header dari kernel itu, tetapi terhenti pada saat itu tampak seperti gejala bahwa sesuatu yang lain belum merilis perangkat MMC, mungkin karena sesuatu gagal selama operasi sebelumnya. Driver sdhost akan mencatat pesan kesalahan, jadi jika pesan kesalahan tidak ada, saya condong ke kotak surat ARM <-> VPU yang berhenti saat mencoba mengkonfigurasi jam untuk antarmuka SD.

Kesalahan seperti ini seringkali menjadi pertanda pasokan listrik yang tidak memadai. Apa yang dilaporkan "vcgencmd get_throttled" pada sistem Anda setelah beberapa aktivitas biasa?

Juga 4.9 sekarang dianggap sebagai versi stabil dari kernel di RPI.

Tidak - ini masih versi berikutnya sampai kami membuat rilis Raspbian menggunakannya.

Itu membingungkan kalau begitu ...

Secara pribadi, saya akan mencoba kartu yang sangat, sangat murah terlebih dahulu untuk mengesampingkan masalah perangkat keras. Seperti jenis yang Anda dapatkan seharga $ 5 di AS. Saya sebenarnya telah mengumpulkan banyak dari mereka selama bertahun-tahun.

Yang saya maksud dengan kartu murah, adalah semua kartu SD ini murah. Saya tidak peduli berapa banyak Anda membayar untuk mereka, mereka pada dasarnya dirancang untuk pasar kamera / camcorder / telepon sehingga mereka biasanya tidak mendapatkan penyalahgunaan sesuatu yang mungkin terjadi setiap saat.

@pelwell Saya benar-benar melihat kotak surat

Saya telah menemukan bahwa terutama di 64 bit, RPI tidak stabil di 1.2GHz. Menyetel maks pada 1.0GHz sepertinya membantu. Tetapi saya juga belum mengesampingkan masalah firmware.

@pelwell Apa header kernel yang Anda butuhkan? Saya menggunakan kernel Raspbian 8 Jessie default
Linux raspberrypi 4.4.34-v7+ #930 SMP Wed Nov 23 15:20:41 GMT 2016 armv7l GNU/Linux .

Catu daya saya tampak stabil dan cukup karena menyimpulkan dari throttled=0x20000 .
Saya memperoleh nilai ini selama uji stres yang menaikkan suhu CPU saya menjadi 80 ° C.

Omong-omong, jika Anda mencari kmmcd mmc_rescan Anda juga akan menemukan orang lain yang melaporkan masalah ini.

Sementara itu saya perhatikan bahwa masalah ini dipicu oleh browser-krom (Versi 51.0.2704.91 Dibangun di Ubuntu 14.04, berjalan di Raspbian 8.0) ketika beberapa situs terbuka.

Harap perbarui ke kernel terbaru yang mungkin membantu, 4.9 sekarang adalah versi rilis. Mohon laporkan kembali hasilnya.

Sayangnya saya masih melihat masalah yang sama setelah peningkatan.
Sementara itu saya menggunakan:
Linux raspberrypi 4.9.24-v7 + # 993 SMP Rabu 26 Apr 18:01:23 BST 2017 armv7l GNU / Linux
dan Chromium Versi 56.0.2924.84 Dibangun di Ubuntu 14.04, berjalan di Raspbian 8.0

Saya tidak pernah melihat ini sebelumnya, dan sekarang melihatnya beberapa kali menjalankan 4.9.80-v7 + selama pengunduhan wget yang sangat cepat. Saya kira inilah yang membuat Raspberry Pi 2 B untuk sementara tidak responsif, tetapi tidak macet dan unduhan tidak gagal.

Apakah ini masih terjadi pada kernel 4.14 terbaru?

Masalah ini akan ditutup dalam 30 hari kecuali interaksi lebih lanjut diposting. Jika Anda ingin masalah ini tetap terbuka, silakan tambahkan komentar. Masalah tertutup dapat dibuka kembali jika diminta.

sayangnya ini adalah:

Oke, kita perlu memahami apa yang terjadi yang mungkin menyebabkan ini. Karena ini tampaknya sangat tidak umum, adakah sesuatu tentang penyiapan Anda yang dapat dianggap agak tidak biasa yang dapat mempromosikannya? Apa yang Anda lakukan saat itu terjadi?

Saya juga memiliki masalah yang sama, chromium-browser yang "macet" setelah beberapa saat (tampilan dibekukan, tetapi log dari pi menunjukkan itu masih "aktif")

Apa yang terjadi adalah karena ini setelah beberapa saat pi mulai mematikan tugas, dan pi berada dalam keadaan zombie. Ini adalah pi yang digunakan untuk dipajang di kafetaria, jadi saya biasanya hanya mem-boot ulang alih-alih mencoba menyambungkannya melalui SSH untuk melihat apa yang terjadi. Lain kali jika macet, saya akan mencoba untuk melihat apakah OS masih responsif atau jika pi benar-benar dalam keadaan zombi.

Pi jatuh sekitar Jul 24 17:20 :

Kita bisa melihatnya "bekerja" meski layarnya membeku.

Saya menemukan hal menarik lainnya:

Tanggalnya tidak cocok, tetapi mungkin ada sesuatu yang perlu digali di sini secara lebih umum.

Yang aneh adalah saya memiliki pengaturan pi lain yang persis sama dan yang ini tidak macet. Saya akan mencoba untuk memeriksa perbedaan versinya, saya pikir hwnya sedikit berbeda juga.

Sama di sini, tetapi itu hanya terjadi sejak saya meningkatkan dari jessie ke peregangan:

Ini terjadi secara teratur setelah beberapa waktu selama penulisan yang relatif berat (perekaman tvheadend) ke folder yang dipasang nfs

'saya juga', dan saya dapat mereproduksinya pada dua 3B + yang berbeda, dengan kartu SD yang berbeda, dan catu daya yang berbeda. Kernel stok di raspbian-stretch-lite 2018-06-27 melakukannya, 4.14.70-v7 + # 1144 melakukannya, 4.14.73-v7 + # 1148 melakukannya.

Ini adalah pemasangan biasa, dengan ssh diaktifkan, dan beban kerja saya cukup berulang: Coba gunakan kartu SD. Loop berjalan:
Tulis data 512 byte acak ke lokasi acak dalam file 2MB, satu juta kali, buang setelah setiap penulisan.
sinkronkan, dan jatuhkan cache.

Terkadang hang sementara cukup lama sehingga saya kehilangan ssh.

Saya punya ide untuk menguji ini pada berbagai model, untuk melihat apakah multicore atau wifi adalah pemicunya: Tidak, ini adalah Pi3 / Pi3B +.

Pi 0W (4pcs): runtime 48 jam, tidak ada kegagalan
Saya menguji 4 kartu (Sandisk A1, industri SanDisk, NetList SLC, Panasonic Industrial), satu di setiap 0W, dengan wifi diaktifkan dan berbicara, dengan total 192 jam kartu.

Pi 2 original (1pc): runtime 48 jam, tidak ada kegagalan
Jika ini adalah bug penguncian, mungkin itu akan gagal di Pi2. Ini adalah Pi2 pertama, tidak menggunakan Pi3 SoC.

Pi 3 asli (1pc): runtime 8 jam, 6 kegagalan, throttled = 0x0
Ini didukung dari pasokan 5V 5A yang sangat bagus dan bersih, dengan kabel pendek yang gemuk, dan heatsink yang besar.

Pi 3B + (3pcs): Sangat bervariasi. Yang terbaik memiliki waktu runtime 6 hari dan hanya satu kegagalan, yang terburuk rata-rata gagal sekali per jam.

Berbagai hal dicoba:
330uF ekstra pada 3.3V. 5V dipasok ke header. Menonaktifkan wifi. Iperf3 pada wifi saat menyalin. Tidak ada perbedaan.

Saya melihat tidak ada pembaruan dalam masalah ini untuk sementara waktu sekarang ...

Juga mendapat masalah ini karena saya telah meningkatkan ke peregangan
Perangkat keras: 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

Saya menjalankan beberapa kontainer buruh pelabuhan, satu menggunakan berbagi NFS mungkin yang menyebabkannya? (penularan)

Saya menggunakan ini untuk memasangnya:

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)

Sejak beberapa minggu saya mengalami kesalahan yang sama. Tapi saya punya raspberry pi 2. Saya punya kartu SD Samsung 32gb di dalamnya. Saya menjalankan influxdb di kartu, di sebelah Hass, grafana, traefik dan Telegraph, semua dalam wadah Docker. Saya memantau statistik raspberry pi, tetapi tidak melihat masalah (cukup memori, tidak ada lonjakan cpu). Mungkin karena terlalu Mach io pada kartu SD? Setelah reboot, semuanya aktif dan berjalan dengan baik, bahkan selama seminggu.

Saya memiliki masalah yang sama sejak beberapa bulan yang lalu, setiap node Cluster Raspberry Pi Kubernetes saya setiap hari (hampir setiap 24 jam) pengecualian itu. Sebagai node saya menggunakan Raspberry Pi 3 B + dan Raspberry Pi 3.

Adakah yang bisa terpengaruh oleh masalah ini, menguji patch upstream ini juga tersedia di rpi-5.1.y?

Saya telah mem-port patch secara lokal kembali ke cabang 4.19.y dan membangun kernel untuk menguji patch tersebut. Sistem di-boot ulang dan jika kesalahan terjadi lagi, itu akan terjadi dalam 24-28 jam ke depan ...

@lategoodbye Sepertinya patch tersebut tidak berfungsi, di pagi hari saya mengalami error yang sama seperti sebelumnya.

@sbiermann Patch tidak ditujukan untuk masalah ini. Jadi itu hanya percobaan.

Akan sangat membantu bagi saya, jika Anda dapat mereproduksi masalah ini dengan mmc / host / bcm2835 (upstream), bukan mmc / host / bcm2835-sdhost (downstream). Keduanya menggunakan DT yang sama yang kompatibel sehingga Anda perlu mengubah konfigurasi kernel yang sesuai (aktifkan MMC_BCM2835 dan nonaktifkan MMC_BCM2835_SDHOST).

Terima kasih

@lategoodbye Maaf, saya tidak begitu terbiasa dengan pembuatan kernel, biasanya saya hanya menggunakan imej kernel default atau dalam beberapa kasus rpi-update kernel yang diberikan. Petunjuk https://www.raspberrypi.org/documentation/linux/kernel/building.md ini telah saya ikuti untuk membangun kernel 4.19.y dengan perubahan driver / dma / bcm2835-dma.c Anda.

Sekarang saya telah mengubah file .config saya jadi saya terlihat seperti:

CONFIG_MMC_BCM2835_MMC = y
CONFIG_MMC_BCM2835_DMA = y
CONFIG_MMC_BCM2835_PIO_DMA_BARRIER = 2
# CONFIG_MMC_BCM2835_SDHOST tidak disetel

Apakah itu benar?

Ya, tetapi Anda juga harus memiliki (maaf tentang nama yang membingungkan)

CONFIG_MMC_BCM2835 = y

Itu tidak berhasil dan merusak kernel, Pi tidak pernah boot. Untuk memulihkan saya telah menyalin kernel lama kembali ke sistem dan sekarang mulai lagi.

Saya telah memecahkan masalah untuk saya, tetapi ini bukan solusi umum. Pokoknya saya jelaskan di sini tempat kerja saya mungkin itu membantu orang lain untuk memecahkan masalah.
Seperti yang ditulis sebelumnya, pengaturan saya adalah cluster raspberry pi kubernetes dengan 3 pekerja dan 1 master. Master dan 2 pekerja adalah Raspberry Pi 3 B + dan satu pekerja adalah Pi 3 B yang lebih lama. Masalah terjadi pada setiap pekerja setelah 24-28 jam ketika pekerja menjalankan perangkat lunak otomatisasi rumah saya yang disebut FHEM. Ketika masalah terjadi, kubernetes menjadwal ulang FHEM untuk dijalankan pada pekerja lain, jadi setiap pekerja memiliki masalah. FHEM mengumpulkan banyak data dari sensor eksternal seperti suhu di ruangan atau nilai dari data pemanas atau angin. Banyak data ini ditulis melalui GlusterFS ke cluster GlusterFS yang didasarkan pada dua Raspberry 1 dengan USB Stick untuk datanya. Kubernetes dan Docker menulis pesan status mereka dan hal-hal lain ke kartu SD lokal. Solusi saya adalah memulai ulang FHEM setiap malam pada pukul 00:05:00 pagi. Setelah itu masalah tidak pernah terjadi lagi, itu berjalan stabil sejak 5. juni. Perintah restart akan mematikan pod kubernetes dan kubernetes me-restart pod setelah beberapa detik. Ini berarti bahwa di latar belakang penampung buruh pelabuhan tempat FHEM dijalankan akan dimatikan dan dimulai ulang.
