Dual Opteron crashes with Kernel Panic

Hi List, i tried to install SuSE 9.2 on FSC V810 Dual Opteron 250 WS with 4 GB Ram. No way. If i boot the standard smp 64 Bit Kernel i get a kernel panic at the boot. If i boot the standard 64 Bit Kernel without smp, everything seems to work fine. As a result from this tests, i have tried to install SuSE 9.1. This Distri boots with the standard smp 64 Bit kernel bit later it's unstable. I.e. X crashes without any comment or log entrys. There are any experiences regarding this problem?? THX Andreas Wahlert
