I get this when starting mpg123 about 50% of the time:

lock order reversal
 1st 0xc8e22f40 pcm0:play:0 @ /usr/src/sys/modules/sound/pcm/../../../dev/sound/pcm/dsp.c:150
 2nd 0xc8e24380 pcm0 @ /usr/src/sys/modules/sound/pcm/../../../dev/sound/pcm/sound.c:134

-current as of yesterday, using the ds1 driver loaded via loader.conf

Probably unrelated, but I also get audible clicks on playback when I move
the mouse in console mode (using moused).

relevent dmesg:
pcm0: <Yamaha DS-1E (YMF744)> port 0xfefc-0xfeff,0xff00-0xff3f mem 0xefff8000-0xefffffff irq 11 at device 12.0 on pci0
atkbdc0: <Keyboard controller (i8042)> at port 0x64,0x60 on isa0
atkbd0: <AT Keyboard> flags 0x1 irq 1 on atkbdc0
kbd0 at atkbd0
psm0: <PS/2 Mouse> irq 12 on atkbdc0
psm0: model IntelliMouse, device ID 3
