[2.5.63] Kernel Panic During Boot (Swap???)

[Mark F.]

hello, heres the situation.  Compiled 2.5.63 with the mod-utils 0.9.9
version.  Kernel worked the first couple of times using it.  but then, while
trying to loaded some changes to it.  It now crashes each time with a Kernel
Panic.  Reverting back to the my saved 2.4.21-pre3 I can still boot.  Also,
undoing the kernel changes isn't kelping me.   Heres some of the code snip
the kernel boot out.  and the location where:  (sorry if there are a couple
of typos, typing it on another machine):  This is redhat 8 based on a Compaq
900z which runs off of the Radeon IGP 320M Chipset.

In interrupt handler - not syncing

I can reproduce this consistantly so far, so will give any information I can
give ya.  I'm gonna go and continue modding the kernel to see if i can break
it down or see the solution.
