That was the answer I was afraid of....  Already tried using git bisect to track 
down a bootmem allocation bug in SGI O2 systems (2.6.17 just broke everything it 
seems...), but the bisection point happened to be around the time when all the 
bitops changes were occuring (moving duplicate functions from asm-mips -> 
asm-generic), resulting in a tree that wouldn't even compile.

Having to patch up a broken tree so it even builds to determine if the bisection 
is good or bad might obscure the bug, but well, guess that's something to try on 
the weekend.

Offhand, though, is there anything I should keep an eye out for that can do 
things like setting mb[] to 0x0 (i.e., things you guys might've seen happen in 
the past?).  And what do those numbers for 'mailbox0', 'ictrl', and 'istatus' 
mean (I'm guessing not much, because they're probably qla1040-specific error 
codes that require chip docs to understand).
