Yes, I have "device apic" in my kernel config file. Is this a bad thing to
do for a UP system?

I remember googling "device apic" and finding at least some info that seemed
to indicate that it was off by default in GENERIC simply because there are a
few I/O APICs that are buggy, and that it actually helped on systems with
properly working chips.

Should I leave it out of my kernel config? (I'm just about to recompile with
Nate's extra debug output patch.)
