Hmm, I think this answer should be for "New <PNP0303> and aPic question"?

Well I tired to build one (with -curr some weeks ago) with device apic only 
which didn't work, I had to add options smp arrrgghhh. Had a look in my file 
and saw I did the following:
#options         SMP
#options         APIC_IO

Seems I didn't use "device apic" (perhaps I didn't recognize)

But regardless, when I built a SMP kernel it didn't run on my UP machine.

Thanks a lot,
