I think I once turned off APIC in the bios but left it compiled in the
kernel, and it still locked up.  Strange.  I think I'll stick with my
current kernel build since it seems to have everything working, and as
you said APIC isn't that big a deal.

Good to know about the XP stuff too.  I ran into that for a while, and
didn't know what was causing it.  If for some reason I need to use XP
for anything in the future this will come in handy.

Thanks again!
