then it's highly likely that your mp table is incorrect.  in bios there is often an
option for mp specification version or some such.  you want to set that to 1.4
if you have it.  unfortunately, i suspect this is not your problem.

i put a version of mp.c on sources (/n/sources/contrib/quanstro/mp.c) that
provides the file #P/mpirq which prints out the mp table irq assignments.
if you can figure out how to save this stuff automatically with mp irqs enabled,
this should have enough information to say for sure.

i feel your pain.  i have a new motherboard with some bad entries in the mp
table, too.
