amd64 kernel crashes during boot on U40

[Kurt Schreiner <ks%ub.uni-mainz.de@localhost>]

Hi,

a -current kernel build from sources cvs updated ~17:45 MDST crashes
during boot on both of my Sun Ultra40's. I tried a GENERIC kernel
and the normally used adapted one: same problem.
As I can't break to ddb and no core dump is generated I can only
provide the last lines of dmesg:

I've tried other kernels w/o fwohci and/or sound but no change....

Any idea what's going on? And how to remedy this? ;-)
