Hello!
For last 3 days I have had some problems with link, and there were
many disconnect/connect tries, short ppp sessions etc.
I found something like this in logs
(with: Linux finwe 2.6.1 #10 Wed Jan 14 13:22:06 CET 2004 i686 GNU/Linux
pppd version 2.4.2 ):

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

Yes it worked, no more badness.
