I've applied the patch above to a pristine 2.5.69-mm6. Curiously, if I
build snd-ymfpci as a module, I can't reproduce the oops anymore.
However, if I build snd-ymfpci into the kernel, I can *still* reproduce
the oops.
Attached is the dmesg of a 2.5.69-mm6 plus the above patch with ymfpci
integrated into the kernel.
Thanks!
