When I try to boot the most recent "2.4-to-be" kernel on a SMP machine
(one CPU only, though), I get a lot of APIC/interrupt errors.
I'm running it on a PII-266 CPU on a 440-FX motherboard.
Due to the fact that these messages fly by at the speed of light ;), I am
unable to be 100% accurate, but here goes:
APIC error
Interrupt accept error
APIC ESR0: 00000004
APIC ESR1: 00000004
(repeated over and over)
The stock 2.2.12 SMP kernel shipped with RedHat 6.1 boots fine.
Here's the dmesg output of that boot:

I've included a little more output than necessary, because I also wanted
to pinpoint the last "VFS" entries. What the heck is this? I also get it
on a second machine, and I've been unable to get rid of it.
Some more diagnostic output follows ...
"lspci" gives -

You would if you could but you can't so you won't.
