I'm able to trigger this consistently by using twinkle with my Plantronics USB wireless headset (I haven't tested without the headset). SIP phone calls will go fine for several minutes, then the audio will get broken, and my logs will be inundated with the above messages. When I click the "Bye" button to hangup the call, my system will hang hard. Just prior to the backtraces appearing, I see this in the logs: Nov 26 13:29:44 dblack kernel: [407807.167418] ALSA sound/usb/clock.c:237 6:1:1: cannot get freq at ep 0x4 Nov 26 13:29:44 dblack kernel: [407807.172047] ALSA sound/usb/clock.c:237 6:2:1: cannot get freq at ep 0x84 Nov 26 13:29:44 dblack kernel: [407807.206411] ALSA sound/usb/clock.c:237 6:1:1: cannot get freq at ep 0x4 Nov 26 13:29:44 dblack kernel: [407807.211161] ALSA sound/usb/clock.c:237 6:2:1: cannot get freq at ep 0x84 Nov 26 13:29:47 dblack kernel: [407809.849783] ALSA sound/usb/clock.c:237 6:1:1: cannot get freq at ep 0x4 Nov 26 13:29:47 dblack kernel: [407809.855362] ALSA sound/usb/clock.c:237 6:2:1: cannot get freq at ep 0x84
This problem only appeared after a recent kernel update from 3.4.11-1.fc16.x86_64 to 3.6.5-2.fc16.x86_64
