Some relevant info. The motherboard is a Tyan K8S Pro
(S2882) with 12 GB of PC2700 ECC memory. If I limit
the memory by setting 'hw.physmem="8G"' in the loader
or in /boot/loader.conf, then the system boots fine.
Any other setting above 8G will result in the above panic.
The panic occurs too earlier to get a crash dump.
However, I'm will to try any patch or settings.
