Fallos de segmentación y pánicos del kernel en una instalación nueva

Question

Sistema:

Dell XPS 9560 (ssd nuevo, tiré el viejo porque pensé que ese era el problema)

Instalar:

Cifrado completo del disco nuevo y único (no arranque dual) utilizando todas las opciones predeterminadas de Ubuntu 19.10 (teclado de EE. UU.)

Problemas:

1. A veces el sistema se bloquea en modo de sólo lectura (dmesg muestra una suma de comprobación no válida en ext4 fs) sin motivo aparente. En el siguiente reinicio, se me presenta initramfs, presiono salir y veo que /dev/mapper/vgubuntu de alguna manera se ha corrompido. fsck -y /dev/mapper/vgubuntuParece solucionar este problema pero sigue sucediendo y no entiendo por qué.
2. Con frecuencia me presentan errores en el registro del sistema sobre la autenticación lvm (y comandos como vgs conducen a una falla de segmentación)
3. Cada vez que hago cambios en el disco (instalo software, etc.), el siguiente reinicio tiene uno de los problemas anteriores o algo similar donde no se puede montar /sys o /proc y provoca un pánico en el kernel.
4. A veces, después de reiniciar, la contraseña de cifrado dirá que es incorrecta cuando sé con absoluta certeza que estoy escribiendo la contraseña correctamente. Esto tiende a suceder después de iniciar desde un USB en vivo o conectar algún otro dispositivo USB.

Una colección de errores que a veces veo en dmesg:
