Can you generate this oops with a kernel compiled with CONFIG_DEBUG_KERNEL enabled to get full backtracing support. Can you tell me if you have tested with the latest development kernel, 2.6.25_rc8 as of this writing.
you probably don't need CONFIG_DEBUG_KERNEL but you do need CONFIG_KALLSYMS
The outputs with CONFIG_DEBUG_KERNEL and CONFIG_KALLSYMS for the kernel 2.6.24-gentoo-r4, 2.6.24-r4 and 2.6.25_rc8 come "immediately". Bogomips: 600 ;-)

Please do the following for the kernel that you posted the oops from above: emerge -n gdb cd /usr/src/linux-whatever rm -f sound/isa/cs4232.o make CONFIG_DEBUG_INFO=y sound/isa/cs4232.o gdb sound/isa/cs4232.o Then at the gdb prompt: list *snd_cs423x_pnp_init_wss+0xd1 and post the output here Thanks
Please reopen when you've had the chance to perform the steps outlined in Comment #5
