Sporadically get: uaudio0: at uhub4, port 2, addr 3 (disconnected) pcm0: unregister: channel pcm0:virtual:dsp0.vp0 busy (pid 2204) pcm0: Waiting for sound application to exit! pcm0: unregister: channel pcm0:virtual:dsp0.vp0 busy (pid 2204) pcm0: Waiting for sound application to exit! pcm0: unregister: channel pcm0:virtual:dsp0.vp0 busy (pid 2204) pcm0: Waiting for sound application to exit! [... -- closing/killing the concerning the application] pcm0: Waiting for sound application to exit! pcm0: unregister: mixer busy pcm0: Waiting for sound application to exit! pcm0: unregister: mixer busy [repeat at infinitum] The usb-stack seems to be completly hung at this point (usbconfig&friends hang) -- until I close everything else that has /dev/mixer* open. Then the device seems to reattach and gets usable again. -- You are receiving this mail because: You are the assignee for the bug.
