panic on boot

[Petr Holub]

Hi,

I was about to install September -CURRENT snapshot on a machine
with 10GE card. When attempting to install from USB CDROM (it's
a 1U machine without, I get something like a kernel panic
with a stacktrace running indefinitely and very fast. I must be
in a very early stage as I was unable to break it anyhow. When
I tried to break in using serial console (setup using BIOS), the
last message I get in the console is
CD Loader 1.2
and then nothing, but the screen keeps running with sth like register
dump.

This behavior also occurs with both i386 and amd64 Sept07 snapshot,
i386 March07 snapshot and i386 FreeSBIE 1.1 which I attempted to run
as well. However, Feisty Fawn runs and installs just fine.

Basically, it's a dual processor dual core (4 cores in total)
Intel Xeon 5160 @ 3GHz with 4GB RAM.

Is there any way to stop this and debug it?

TIA,
Petr
