Description of problem:
2.4.9-31smp on my old-but-trusty i586 SMP system (Dec Celebris XP 5133) dies
with an OOps in IO_APIC_get_PCI_irq_vector.

Steps to Reproduce:
1.Boot with the 2.4.9-34smp kernel
2.Sit back and watch
Actual Results: Oops!
Expected Results: Whee! (aka, actual booting)
Can you attach the output of dmesg to this bug of the successful boot with 2.4.9-31?
(eg "dmesg > filename" and then "Create new attachement on this page)
That way I can see how things are supposed to be

2.4.9-31smp boot log
Note, BTW, that the 2.4.9-34 (non-smp) also boots fine on this hardware.
I do have a "suspect" for the failure, eg we added a patch to enable some bigger
systems (with more than 32 PCI slots); this is the only change between -31 and
-34 that touches such early boot stuff. I'll investigate your dmesg output to
try to find out why it breaks.
From the ChangeLog, I made a wild guess that it could be:
"- Add I/O SAPIC IA64 patch, fixes #63952"
since that was the only thing I saw that mentioned the APIC stuff, although as
an IA64 patch, it didn't seem all that likely (?). Glad you have a possible
area to look.
If you'd like me to try out a candidate fix for the bug, I'd be happy to do
that. Just point me at an RPM that's ready to go.
*sigh* I won't be able to help you track down the problem after all.
The machine concerned just died. :-( I guess all the recent reboots
just didn't sit well with it or something. :-( :-( :-(
As it seems, I am having this *exact* same problem with kernel-smp-2.4.9-34.i586.rpm on
my Dual P100-based Dell Optiplex DGX 5100 system. Is there something I can try?
please try "noapic" as kernel option...
Thanks! That did it!
