Description of problem:
Booting the Fedora Core 1 SMP kernel with "acpi=on" causes a kernel
panic. This is a regression from the Fedora Core test releases. ACPI
is required for proper interrupt routing on this board (see bug #92417).
I have tried both "acpi=ht" and "pci=acpi". These options both give
me the non-ACPI behavior (the system boots, but USB devices aren't
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot Fedora Core 1 SMP kernel with "acpi=on".
Actual Results: Kernel panic
Expected Results: No kernel panic; USB devices should be recognized.
Bug #92417 has a bunch of information about this system.
kernel-smp-2.4.22-1.2111.nptl works like a champ with "acpi=on".

Can you dump the oops here too ?

kernel oops output
This bug (along with bug #92417) still exists on 2.4.22-1.2129.nptlsmp.
Keeping in mind that this is a regression, what can I do so that I'm
not stuck running 2.4.22-1.2111.nptlsmp forever?
This is weird. The oops appears to be caused by the fact that
CONFIG_DEBUG_SLAB is turned off in 2115. It was on in 2111.
So CONFIG_DEBUG_SLAB=y makes the oops go away.
Still true on updated kernel?
Thanks for the bug report. However, Red Hat no longer maintains this version of
