I keep getting lots of /usr/src/sys/kern/kern_sysctl.c:1002: could sleep with "drm memory" locked from @/dev/drm/drm_memory.h:217 and /usr/src/sys/vm/uma_core.c:1330: could sleep with "pcm0" locked from /usr/src/sys/dev/sound/pcm/sound.c:134 /usr/src/sys/vm/uma_core.c:1330: could sleep with "pcm0:fake" locked from /usr/src/sys/dev/sound/pcm/channel.c:677 /usr/src/sys/vm/uma_core.c:1330: could sleep with "pcm0:play:0" locked from /usr/src/sys/dev/sound/pcm/channel.c:677 /usr/src/sys/vm/uma_core.c:1330: could sleep with "pcm0:record:0" locked from /usr/src/sys/dev/sound/pcm/channel.c:677 for long time. I don't know, how serious these are and how much work is required to fix it. Otherwise it's proabably just a slight nuisance hidden for most users (once GENERIC is without WITNESS). I use both as modules but I'm pretty sure I had the same problem with both compiled into the kernel. In case it matters sound device is detected as: pcm0: <VIA VT82C686A> port 0xe400-0xe403,0xe000-0xe003,0xdc00-0xdcff irq 12 at device 7.5 on pci0 pcm0: ac97 codec id 0x49434511 (ICEnsemble ICE1232) pcm0: ac97 codec features headphone, 18 bit DAC, 18 bit ADC, 5 bit master volume, Reserved 27 pcm0: ac97 primary codec extended features variable rate PCM, AMAP and video is drm0: <3dfx Voodoo3 3000> port 0xc000-0xc0ff mem 0xd8000000-0xd9ffffff,0xd4000000-0xd5ffffff irq 10 at device 0.0 on pci1 info: [drm] Initialized tdfx 1.0.0 20010216 on minor 0 The complaints about "drm memory" are shown in groups of about 25 same messages on each invocation of 'sysctl hw.dri' (or -a) but otherwise they seem to be quiet. The complaints about pcm happen only on boot (about 30). I'm ready to send more detail if required but I suppose it's going to be general problem - I've seen it mentioned (at least the pcm one) several times.
