Kernel Panic at 1st boot time

Hi, there, I've just downloaded, burned and install 32-bit version of 64studio. Almost everything seemed to be fine(except network setup, which said "Incorrect Machine name '''' ", and something else), but when I tried to boot from my hdd(normal boot or single user), it interrupted and print registers' values

my hardware are:

Cel 2000
ECS i845G motherboard
nVidia GF2-MX400
Creative SB Live 5.1

I had standard lenny

I had standard lenny distribution on this machine

it works good with 2.6.24 kernel,
but had similar problem with 2.6.25-2 and 2.6.22-rt4 from Musix repository
