Linux: Cola de trabajo: bloqueo de kmmcd mmc_rescan con el kernel de Raspbian 4.4.38-v7

Mi Raspberry Pi 3 funciona de forma inestable y se bloquea cada pocos días. Antes del bloqueo, / var / log / messages muestra el siguiente error repetidamente con una separación de unos minutos:

Estoy ejecutando Raspbian 8.0 (Jessie) con kernel

Linux raspberrypi 4.4.38-v7 + # 938 SMP Jue. 15 de diciembre 15:22:21 GMT 2016 armv7l GNU / Linux

También estoy discutiendo esto en

http://raspberrypi.stackexchange.com/q/61050/58211.

También informé esto en https://github.com/raspberrypi/firmware/issues/731 pero creo que encaja mejor aquí. Desafortunadamente, no puedo mover el problema, por lo que ahora es una especie de duplicado. Quizás debería eliminarse en el firmware.

  1. ¿Está sobreacelerando el RPI?
  2. ¿Has probado una tarjeta SD diferente? Sé que estas tarjetas baratas pueden desgastarse o romperse después de haberlas usado por un tiempo. Y son relativamente baratos, por lo que podría valer la pena probar un reemplazo.

Dudo que esto sea un problema de firmware. En realidad, podría ser una combinación de una tarjeta defectuosa más un error en el controlador. Es muy posible que el conductor crea que ha retirado la tarjeta aunque no lo haya hecho. Y dado que sacar la tarjeta SD mientras se está ejecutando el RPI es un no-no, pude ver por qué eso podría no haber sido probado bien.

Sé que se está haciendo un esfuerzo para reemplazar este controlador con una versión anterior. Además, 4.9 ahora se considera la versión estable del kernel en el RPI.

  1. No, no cambié la velocidad del reloj.
  2. Es un Samsung MicroSDXC 128GB EVO Plus UHS-I Grade 1 Class 10 de gama alta de 40 EUR que tiene dos particiones de 8 GB para / root y / home.

He probado completamente la tarjeta con badblocks -w con los 5 patrones diferentes antes del uso y no encontré un solo bloque defectuoso. Una prueba de lectura reciente de badblocks tampoco mostró ningún error. Asumo que la tarjeta es perfecta.

Acabo de pedir otro Pi 3 y un SanDisk Ultra 64GB SDXC (80 MB / Sek) Class 10 para descartar problemas de hardware.

Se perdió el encabezado de ese kernel, pero un bloqueo en ese punto parece un síntoma de que algo más no ha liberado el dispositivo MMC, posiblemente porque algo falló durante una operación anterior. El controlador sdhost registrará mensajes de error, por lo que, en ausencia de ellos, me inclino hacia el bloqueo del buzón de correo ARM <-> VPU mientras intento configurar el reloj para la interfaz SD.

Errores como este suelen ser el signo de una fuente de alimentación inadecuada. ¿Qué informa "vcgencmd get_throttled" en su sistema después de alguna actividad típica?

Además, 4.9 ahora se considera la versión estable del kernel en el RPI.

No, sigue siendo la próxima versión hasta que hagamos una versión de Raspbian usándola.

Eso es desconcertante entonces ...

Personalmente, primero habría probado una tarjeta muy, muy barata para descartar un problema de hardware. Como el tipo que obtienes por $ 5 en los EE. UU. De hecho, he recopilado un montón de esos a lo largo de los años.

Lo que quise decir con tarjetas baratas es que todas estas tarjetas SD son baratas. No me importa cuánto pague por ellos, están diseñados esencialmente para el mercado de cámaras / videocámaras / teléfonos, por lo que generalmente no reciben el abuso de algo que puede estar encendido todo el tiempo.

Electron752 picture Electron752 en 10 mar. 2017

@pelwell En realidad veo buzones de correo de vez en cuando y no estoy 100% seguro de que sea la fuente de alimentación, ya que a veces puedo verla incluso si el RPI está conectado a una fuente de alimentación variable de banco que puede hacer 5 amperios.

Descubrí que, especialmente en 64 bits, el RPI es inestable a 1,2 GHz. Establecer el máximo en 1.0GHz parece ayudar. Pero tampoco descarté un problema de firmware.

Electron752 picture Electron752 en 10 mar. 2017

@pelwell ¿Qué cabecera de kernel necesitas? Estoy usando el kernel predeterminado de Raspbian 8 Jessie
Linux raspberrypi 4.4.34-v7+ #930 SMP Wed Nov 23 15:20:41 GMT 2016 armv7l GNU/Linux .

Mi fuente de alimentación parece estable y suficiente como se concluyó en throttled=0x20000 .
Obtuve este valor durante una prueba de esfuerzo que elevó la temperatura de mi CPU a 80 ° C.

Por cierto, si busca en Google kmmcd mmc_rescan , encontrará a otras personas que también informan sobre este problema.

Mientras tanto, noté que este problema lo desencadena el navegador chromium (Versión 51.0.2704.91 Construido en Ubuntu 14.04, que se ejecuta en Raspbian 8.0) cuando varios sitios están abiertos.

fkbreitl picture fkbreitl en 18 mar. 2017

Actualice al último kernel que puede ayudar, 4.9 es ahora la versión de lanzamiento. Informe los resultados.

Desafortunadamente, sigo viendo el mismo problema después de la actualización.
Mientras tanto estoy usando:
Linux raspberrypi 4.9.24-v7 + # 993 SMP Mié 26 de abril 18:01:23 BST 2017 armv7l GNU / Linux
y Chromium Versión 56.0.2924.84 Construido en Ubuntu 14.04, que se ejecuta en Raspbian 8.0

Nunca vi esto antes, y ahora lo vi un montón de veces ejecutando 4.9.80-v7 + durante una descarga de wget muy rápida. Supongo que esto es lo que hizo que la Raspberry Pi 2 B dejara de responder temporalmente, pero no se bloqueó y la descarga no falló.

¿Sigue sucediendo esto en el último kernel 4.14?

Este problema se cerrará dentro de los 30 días a menos que se publiquen más interacciones. Si desea que este problema permanezca abierto, agregue un comentario. Un problema cerrado puede reabrirse si se solicita.

Está bien, tenemos que comprender qué está pasando que podría causar esto. Dado que esto parece ser muy poco común, ¿hay algo en su configuración que pueda considerarse un poco inusual que pueda promoverlo? ¿Qué haces cuando sucede?

JamesH65 picture JamesH65 en 23 jul. 2018

También tengo el mismo problema, chromium-browser que "falla" después de un tiempo (la pantalla está congelada, pero los registros del pi sugieren que todavía estaba "encendida")

Lo que sucede es que debido a esto, después de un tiempo, el pi comienza a matar tareas y el pi se encuentra en un estado algo así como zombie. Este es un pi que se usa para mostrar en la cafetería, por lo que generalmente lo reinicio en lugar de intentar conectarme a él a través de SSH para ver qué está pasando. La próxima vez que se bloquee, intentaré ver si el sistema operativo sigue respondiendo o si el pi está realmente en algún tipo de estado zombi.

Podemos ver que "funciona" incluso aunque la pantalla esté congelada.

He encontrado otra cosa interesante:

Las fechas no coinciden, pero tal vez haya algo para investigar aquí de manera más general.

Lo extraño es que tengo otra configuración de pi exactamente de la misma manera y esta no falla. Intentaré comprobar las diferencias de versión, creo que el hw también es un poco diferente.

'yo también', y puedo reproducirlo en dos 3B + diferentes, con diferentes tarjetas SD y diferentes fuentes de alimentación. El kernel estándar en raspbian-stretch-lite 2018-06-27 lo hace, 4.14.70-v7 + # 1144 lo hace, 4.14.73-v7 + # 1148 lo hace.

Esta es una instalación sencilla, con ssh habilitado, y mi carga de trabajo es bastante repetitiva: intente desgastar la tarjeta SD. El bucle va:
Escriba datos aleatorios de 512 bytes en ubicaciones aleatorias en un archivo de 2 MB, un millón de veces, vaciando después de cada escritura.
sincronizar y soltar los cachés.
compare el contenido del archivo con la "verdad".
utilice dd para leer y probar toda la tarjeta.

kkpdk picture kkpdk en 3 oct. 2018

Tuve la idea de probar esto en varios modelos, para ver si el disparador era multinúcleo o wifi: No, es Pi3 / Pi3B +.

Pi 0W (4 piezas): 48 horas de tiempo de ejecución, sin fallas
Probé 4 tarjetas (Sandisk A1, SanDisk industrial, NetList SLC, Panasonic Industrial), una en cada 0W, con wifi habilitado y hablando, para un total de 192 horas de tarjeta.

Pi 2 original (1pc): 48 horas de ejecución, sin fallas
Si se trata de un error de bloqueo, tal vez falle en el Pi2. Este es el primer Pi2, que no usa el Pi3 SoC.

Pi 3 original (1pc): 8 horas de tiempo de ejecución, 6 fallas, acelerado = 0x0
Esto se alimenta de una fuente de 5V 5A realmente agradable y limpia, con cables cortos y gruesos y un gran disipador de calor.

Pi 3B + (3 piezas): Altamente variable. El mejor tiene 6 días de tiempo de ejecución y solo una falla, el peor falla una vez por hora en promedio.

Se probaron varias cosas:
330uF extra en 3.3V. 5V suministrados al cabezal. Desactivación de wifi. Iperf3 en wifi mientras copia. Ninguna diferencia.

Desde hace un par de semanas tengo el mismo error. Pero tengo una frambuesa pi 2. Tengo una tarjeta SD Samsung de 32 GB. Estoy ejecutando influxdb en la tarjeta, junto a Hass, grafana, traefik y Telegraph, todos en contenedores Docker. Superviso las estadísticas de la Raspberry Pi, pero no veo ningún problema (memoria suficiente, sin picos de CPU). ¿Tal vez sea porque también Mach io en la tarjeta SD? Después de un reinicio, está funcionando bien, incluso durante una semana.

Tengo el mismo problema desde hace unos meses, cada nodo de mi Raspberry Pi Kubernetes Cluster tiene todos los días (casi cada 24 horas) esa excepción. Como nodos utilizo Raspberry Pi 3 B + y Raspberry Pi 3.

¿Alguien que se vea afectado por este problema, puede probar este parche ascendente también disponible en rpi-5.1.y?

lategoodbye picture lategoodbye en 1 jun. 2019

He portado el parche localmente de nuevo a la rama 4.19.y y compilé el kernel para probar el parche. El sistema se reinicia y si el error vuelve a ocurrir, será en las próximas 24-28 horas ...

@lategoodbye Parece que el parche no funciona, por la mañana tengo los mismos errores que antes.

@sbiermann El parche no está diseñado para este problema. Así que fue solo un intento.

Sería útil para mí si pudiera reproducir este problema con mmc / host / bcm2835 (upstream) en lugar de mmc / host / bcm2835-sdhost (downstream). Ambos usan el mismo compatible con DT, por lo que deberá cambiar la configuración de su kernel en consecuencia (habilite MMC_BCM2835 y deshabilite MMC_BCM2835_SDHOST).

Gracias

@lategoodbye Lo siento, no estoy tan familiarizado con la construcción de un kernel, normalmente uso solo imágenes predeterminadas del kernel o, en muy pocos casos, rpi-update dado el kernel. Estas https://www.raspberrypi.org/documentation/linux/kernel/building.md instrucciones que he seguido para construir un kernel 4.19.y con sus cambios de los controladores / dma / bcm2835-dma.c.

Ahora he cambiado mi archivo .config, por lo que se ve así:

CONFIG_MMC_BCM2835_MMC = y
CONFIG_MMC_BCM2835_DMA = y
CONFIG_MMC_BCM2835_PIO_DMA_BARRIER = 2
# CONFIG_MMC_BCM2835_SDHOST no está configurado

¿Es eso correcto?

Sí, pero también debe tener (perdón por los nombres confusos)

CONFIG_MMC_BCM2835 = y

Eso no funciona y rompe el kernel, el Pi nunca arranca. Para recuperar, he copiado el kernel antiguo en el sistema y ahora se inicia de nuevo.

He resuelto el problema por mí, pero no es una solución general. De todos modos, describo aquí mi solución, tal vez ayude a otros a resolver el problema.
Como se escribió anteriormente, mi configuración es un clúster raspberry pi kubernetes con 3 trabajadores y 1 maestro. El maestro y 2 del trabajador son Raspberry Pi 3 B + y un trabajador es un Pi 3 B anterior. El problema ocurre en todos los trabajadores después de 24 a 28 horas cuando el trabajador ejecuta mi software de automatización del hogar llamado FHEM. Cuando ocurre el problema, kubernetes reprograma FHEM para que se ejecute en otro trabajador, por lo que todos los trabajadores tienen el problema. FHEM recopila muchos datos de sensores externos como la temperatura en las habitaciones o los valores de los datos de calefacción o viento. Esta cantidad de datos se escribe a través de GlusterFS en un clúster de GlusterFS que se basa en dos Raspberry 1 con memorias USB para los datos. Kubernetes y Docker escribieron sus mensajes de estado y otras cosas en la tarjeta SD local. Mi solución es reiniciar FHEM todas las noches a las 00:05:00 am. Después de eso, el problema nunca volverá a ocurrir, se está ejecutando de forma estable desde el 5 de junio. El comando de reinicio apaga el pod de kubernetes y kubernetes reinicia el pod después de unos segundos. Esto significa que, en segundo plano, el contenedor de la ventana acoplable en el que se ejecuta FHEM se apagará y reiniciará.
