SubjectRe: 2.4.10: Crash on boot with trident driver non-module
From
Date
Well, I realized that the EIP wasn't typed in correctly.  the l was
supposed to be a 1. The new output is:

>>???; c01ba1ce <ac97_init_mixer+7e/e0> <=====
Trace; c01bae74 <pci_announce_device+34/50>
Trace; c01baed2 <pci_register_driver+42/60>
Trace; c0105000 <_stext+0/0>
Trace; c0105049 <init+9/140>
Trace; c0105000 <_stext+0/0>
Trace; c0105536 <kernel_thread+26/30>
Trace; c0105040 <init+0/140>

Hope this helps. I am having a hard time seeing where the changes in
2.4.9 would cause this NULL dereference in ac97_init_mixer when it is
compiled in but not when it is a module.
