Hello everybody,
I'm getting a lock order reversal from pcm over last days,
which look like this:
Dec 15 16:47:54 mephisto kernel: lock order reversal
Dec 15 16:47:54 mephisto kernel: 1st 0xc390e640 pcm0 @ ../../../dev/sound/pcm/sound.c:132
Dec 15 16:47:54 mephisto kernel: 2nd 0xc390e500 pcm0:play:0 @ ../../../dev/sound/pcm/sound.c:189
I don't know if this is important, but I also get complete freezes of my box somtimes
and I don't know if there is a connection between this two things
Here are some additional information:
# cat /dev/sndstat
