SubjectLatest Linus tree oopses on Nehalem box
Hi,

I am seeing this one with the latest Linus' git tree as of this morning
on a Nehalem box. Using the defconfig + megaraid driver.

Not sure if this is already fixed, or if someone already knows whats
wrong? Smells like a yet another BIOS bug - yes the BIOS on this thing
is rubbish.

Cheers,
Jes
