Those error messages are annoying; they don't use dev_err(), so they don't include the device and driver names. There's no way to know what they refer to. I rather suspect they come from the usbaudio driver. When you ran this test, did you have commit 815fa7b91761 applied? Does the same problem occur without Manjunath's changes?
