This happens at shutdown when alsa is to be closed with kernel 2.6.4-mm.
I'm running debian sid, snd_via82xx compiled as module.
Happens also on 2.6.4-rc2-mm1, I can try on more kernels as well if it
is not a clear case.


I slapped a printk on these just before the badness:
de->subdir->name = "id", de->name = "card0"

Badness in remove_proc_entry at fs/proc/generic.c:667
