Ahoj,
před asi dvěma měsíci se začaly dít divný věci. Bootování (konkrétně při kroku "Waiting to be /dev fully populated") se přeruší na hodí to na mě "Kernel panic: not syncing" (a dál si tu chybu nepamatuju...). Po chvíli googlování jsem našel řešení - použil jsem parametr ide=nodma a systém naběhl.
Systém pak nabíhal v pohodě několikrát i bez toho parametru, ale jednoho dne zase kernel panic. Dneska už bez toho parametru skoro nikdy nenabootuju.
Nevíte náhodou, co se to děje? A co dělá ten zázračný parametr ide=nodma? Nerozbíjí se mi náhodou postupně disk?
Díky za odpovědi.
Systémové informace: Debian Squeeze-Wheezy, kernel 2.6.32-5 (a nechci upgradovat na novější, mám s nimi špatné zkušenosti)
