He estado usando pop os (actualmente tengo la última versión basada en Ubuntu 20.04) con mi lenovo x1 extreme gen 1 muy felizmente por un tiempo (2-3 años), pero recientemente me encontré con lo que posiblemente sea un problema de hardware relacionado con el SSD (computadora portátil). falla aleatoriamente y genera errores ext4-fs y systemd-journald) que persisten después de una nueva instalación. Adjunto algunas capturas de pantalla a continuación, pero también colocaré un registro de errores que pude encontrar en el directorio de registros a continuación.

En dmesg, también vi un montón de errores relacionados con la temperatura, aunque no sé qué tan grave es (aunque dado que el umbral es 81 ° C, eso es un poco preocupante).

Finalmente, cuando instalo popos (lo cual hice muchas veces durante el último mes debido a este problema), tal vez uno de cada dos intentos el instalador falle en la etapa de extracción. Funciona cuando lo vuelvo a intentar un par de veces sin cambiar nada con el USB en vivo o cualquiera de las configuraciones de instalación, por lo que también parece un error aleatorio de lectura/escritura. El registro de instalación también parece revelar un error de entrada/salida. Cabe destacar entradas como:

Información extra:
También hice algunas de las pruebas de diagnóstico de memoria que vienen incluidas con la computadora portátil, ninguna de las cuales arrojó ningún error (no las publico aquí a menos que alguien lo solicite).
Después de cada reinstalación de Linux, el problema reaparece después de un tiempo (aunque creo que tarda más en aparecer si intento mantener el disco lo más vacío posible). Además, la opción "actualizar" en la instalación no parece ayudar. Tengo que reinstalar Linux por completo.
INTENTOS DE ARREGLO:
Cuando hago una nueva instalación de Linux, este problema suele reaparecer después de unos días y parece estar relacionado con la cantidad de cosas que pongo en mi disco duro. Si intento intencionalmente mantenerlo al mínimo, parece que tomará más tiempo antes de que ocurra el bloqueo. El último bloqueo ocurrió cuando estaba realizando algunas operaciones de lectura y escritura semiintensivas (un par de 100 MB) a través de Python.
Hay una pista en la wiki de arch-linux (https://wiki.archlinux.org/index.php/Solid_state_drive/NVMe) que dice
Errores de la unidad Samsung en Linux 4.10
En Linux 4.10, pueden ocurrir errores en la unidad y causar inestabilidad en el sistema. Esto parece ser el resultado de un estado de ahorro de energía que la unidad no puede utilizar. Agregar el parámetro del kernel nvme_core.default_ps_max_latency_us=5500[4][5] deshabilita el estado de ahorro de energía más bajo, evitando errores de escritura.
El mío también es Samsung (ver más abajo para más detalles), así que hice lo que se sugiere, pero esto no parece ayudar.
Actualicé todo mi firmware a través de lfvs, aunque no había actualizaciones de SSD allí, principalmente BIOS. Esto resolvió algunos otros problemas pero no este problema en particular.
Sin embargo, no tengo muchas ideas sobre cómo proceder, ya que casi no tengo conocimiento sobre hardware y no quiero ingresar parámetros aleatorios del kernel de los que no sé nada.
Puedo actualizar registros completos si así lo solicita.
Respuesta1
Parece que tienes un problema con el dispositivo de hardware NVMe. Podría intentar arrancar desde una imagen USB de recuperación y ejecutarlo badblocksen el dispositivo NVMe, o si hay una herramienta de diagnóstico de Samsung para borrar/probar el dispositivo, ¿podría ejecutarla?
