I have:

Tried test8 and, now, test9 and both exhibit same problem.

The issue seems to be related to the PnPBIOS support under the Plug and Play Kconfig category. When enabled I get a crash of the form:

Your stack pointer became misaligned. I thought Manfred fixed that?
You don't have nmi_watchdog enabled on the kernel boot command line
do you?

I fixed the double-oops caused by misaligned stack pointers, and the oops if kmem_cache_alloc is called with an misaligned stack pointer.
In this case it seem to be an oops in the bios itself.

Gary: did it work with 2.4? Are there any bios upgrades you could try? My guess is that the bios is just buggy.
