OOPS kernelu 2.2.18 - long

[Jaroslav Stribrsky]

Ahoj,

objevil se mi problem - mam Linux RH6.2, zazaplatovany, upravene a
prekompilovane jadro 2.2.18. Po mesici a pul bezproblemoveho provozu mi
zacalo OOPSovat jadro. Prohnal jsem to pres ksymoops, ale moudrej z toho
nejsem. Najde se nekdo, kdo mi poradi co/kde je problem ? Poprve to
udelal pres ctyrmi dny, podruhe dnes rano (v noci). Pochopil jsem, ze
posledni proces ktery spoustel pred oopsem bylo spusteni crondu.

V messages mam nasledujici vypis
