Confirmed. The watchdog hang bisects right down to commit 9ce650a75a3b
("ALSA: usb-audio: Reduce latency at playback start").

And reverting it on top of my tree also fixes the hang, so it's not
some bisection fluke.

I have no idea what is actually wrong with that commit, but it most
definitely is the problem, and I have reverted it in my tree so that I
can continue merging stuff tomorrow.
