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!
