Suspending works, but when I resume again I get a kernel panic. The
strange thing is that it doesn't dump core onto the swap device, although
I configured dumpdev in /etc/rc.conf. So I only have this info from the
panic:

pcm0: detached
csa: card is Thinkpad 600X/A20/T20
pcm0: <CS461x PCM Audio> on csa0
wakeup from sleeping state (slept 00:00:15)
ata0: resetting devices ..
done
ata1: resetting devices ..
done
pcm0: unregister: mixer busy
csa: card is Thinkpad 600X/A20/T20
panic: resource_list_alloc: resource entry is busy

syncing disks, buffers remaining... panic: bwrite: buffer is not busy???
Uptime: 2m7s
Dumping 255 MB                      <----- it says so, but it doesn't dump

Did the APM code change so much? All that worked perfectly under 4.7.

Another question: what's that hint.apm.0.flags="0x20" in
/boot/device.hints for?

Oh, how can I do that?
