Hi,
I'm trying to get usb sound working in full-duplex, but still no
success.
Once it worked (on 5.3 with patches from appropriate PRs), and then
it began to fail.
I've tried to use that at 5.4, then at 6.0-CURRENT - that, with
GENERIC kernel produced some interesting kernel output (on 5.3 and
5.4 I didn't used KDB, WITNESS and INVARIANTS).
The machine is cvsupped just before build, and `uname -a` produces:

src/sys/GENERIC i386
I've got following:
Jun 14 18:56:03 pager kernel: Sleeping on "usbsyn" with the following
non-sleepable locks held:
kernel: exclusive sleep mutex pcm0:record:0 (pcm record channel) r =
0 (0xc2494840) locked @ /usr/src/sys/modules/sound/sound/../../../dev/

sample code to reproduce, dmesg and kernel logs are attached.
Few word about kernel logs: Start message were sent to syslog via
logger just before program was executed. ``Now will shutdown''
message were sent just before signaling to program. Program had done
some cycles before this message.
