Zdravim, mam na jadre 2.6.19.2 spravene LVM na 3x250GB diskoch, ktore su pripojene na IDE PCI radic ktory sa v linuxe hlasi ako IT8212. Pri boote sa to hlasi vsetko takto:

Najskor vsetko fungovalo normalne, ale teraz je ten problem, ze ked chcem na to pole nieco zapisat tak vidim v dmesg taketo nieco:
