[alsa-devel] usx2y: "should not be here with counts=40" then hard lockup (linux 4.9.0)

[Jaime T]

Hi all.

I'm running a fresh and cleanly-installed debian stable (stretch) with
my tascam us-122. After several hours of perfect sound, the kernel
(4.9.0-2-686) emits:

Dec  4 22:30:20 piano kernel: [14707.140766] should not be here with counts=40
Dec  4 22:30:24 piano jackd[793]: ALSA: poll time out, polled for 3999073 usecs
Dec  4 22:30:24 piano jackd[793]: JackAudioDriver::ProcessAsync: read
error, stopping...

and my jack server stops working, followed soon after by a hard
lockup. I've run alsa-info.sh and the results are available at
http://www.alsa-project.org/db/?f=e2385306145a37956360def8fe06e8c0f951839d

Should I log a bug at https://bugzilla.kernel.org/ ?

Many thanks, Jaime
