Course, the APIC errors themselves just cause delivery retries AFAIK,
so while annoying they shouldn't be a huge problem (outside of the fact
that the syslog will write to disk, possibly generating more interrupts
and an awfully vicious cycle could ensue)

FWIW, noapic helps (a *lot* in many cases), but as per linux-abit reports,
a recent bios (first QQ beta bios works best for me) is the ultimate step
for getting better BP6 results. My home dual celery 366 never stayed up
more than 2 hours before the BIOS upgrade. It's been up around 3 months
since.

I still get an occasional X lockup (forces a kill -9 from an ssh session
and a couple of X restarts to get the video working again) under some
specific xscreensaver modes (only under XF 3.9.x and XF 4, though... still
tracking down the problem), so I have it fixed in Matrix for now.

Of course, turn off all power management and avoid the HPT366 if possible
(again, varies board to board)

Makes me want to buy Abit a license for the Quad board verification
tool so they can finally see where their problems are (not that it'd
help us poor BP6 owners)
