Lock order reversal while playing mp3s
I get the following lock order reversal when playing mp3s on my Vaio PCG-F807K laptop: lock order reversal 1st 0xc399a840 pcm0:play:0 @ /usr/src/sys/modules/sound/pcm/../../../dev/sound/pcm/dsp.c:936 2nd 0xc399ad80 pcm0 @ /usr/src/sys/modules/sound/pcm/../../../dev/sound/pcm/sound.c:132 simond@laptop:~$ cat /dev/sndstat FreeBSD Audio Driver (newpcm) Installed devices: pcm0: Yamaha DS-1E (YMF744) at memory 0xfedf8000 irq 9 (4p/2r/0v channels duplex default) My dmesg is attached. -- Simon Dick [EMAIL PROTECTED] Why do I get this urge to go bowling everytime I see Tux?
