Hola gente, estoy teniendo un problema desde hace unos dias:

Venia bien con mi debian testing pero varias veces al encender la PC, me
aparecian errores en pantalla,
el filesystem se me montaba como solo lectura y arrancaba el fsck (Nota: No
hubo corte de energia ni nada similar,
la PC siempre se apaga ordenadamente).

Cansado de esto reinstalé el sistema, durante un dia estuvo todo perfecto y
ahora de nuevo lo mismo.. errores.
Lo curioso es que en otra partición tengo un windows xp para pruebas y anda
perfecto.
Estuve pensando en dejar de usar ext4 y probar con otro filesystem pero no
creo que el problema pase por ahi.

Acá abajo dejo un par de lineas con los tipicos mensajes que me aparecen
cada tanto. Alguien tiene idea que puede
estar pasando? El HD es un WD de 1tera que lo compre hace 6 meses
aproximadamente.
