Both 1 and 2 are true; 3 still allows the computer to boot normally into
Linux. I haven't had a chance to look at the kernel yet, but my guess is
that the problem is that the either kernel does not disable the local APIC
before rebooting or it needs some fix for cases when the BIOS is at fault
(which is most likely the case here). For now, I recommend just disabling
it since it does not seem to have any performance difference (at least on my
system); people who need it could enable it easily enough.
