Hello everybody,
over the last few days I get this lock order reversal
and also my box freezes somtimes. I don't know if there
is a connection but I think it might be of interest.
If not ignore this mail ...

This I see in /var/log/messages:
Dec 15 16:47:54 mephisto kernel: lock order reversal
Dec 15 16:47:54 mephisto kernel: 1st 0xc390e640 pcm0 @ ../../../dev/sound/pcm/so
Dec 15 16:47:54 mephisto kernel: 2nd 0xc390e500 pcm0:play:0 @ ../../../dev/sound

My X freezes very often in the last time , and I have to kill the server,
but somtimes the hole box freezes and i have to do a hard reset.
This is the only thing I found in the logs.

here is some additional information:
#cat /dev/sndstat
