Kernel panic: cim to je? (dlouhe)

[Pavel Lisy]

Dobry den

po nekolika mesicnim bezproblemovem provozu se mi v poslednich nekolika
dnech zacali v logu objevovat hlasky o hrouceni kernelu a system
prestava v techto pripadech samozrejme fungovat. Bohuzel me nenapada ani
po prohlednuti logu, cim to muze byt? Nic jsem v nastaveni ani v
instalaci nemenil, alespon si na nic vyznamneho napamatuji. Mam proto
podezreni na HW, ale netusim, cim konkretne by to mohlo byt.

Ze by prehrivani procesoru nebo disku? Nebo odesla pamet. Prikladam
vypis z logu. Nesetkal jste se nekdo s necim podobnym?

Pavel
