Hi , i am doing usb audio streaming over usb audio class interface . whenever i do a usb disconnect during audio streaming , linux kernel get stucks into this infinite loop and the system simply stucks . i get these log messages infinitely : ALSA sound/usb/usbaudio.c:354: frame 0 active: -71 ALSA sound/usb/usbaudio.c:354: frame 0 active: -71 ALSA sound/usb/usbaudio.c:354: frame 0 active: -18 ALSA sound/usb/usbaudio.c:354: frame 0 active: -18 ALSA sound/usb/usbaudio.c:354: frame 0 active: -18 ALSA sound/usb/usbaudio.c:354: frame 0 active: -18 1) i am using linux kernel version 2.6.30.9 . 2) what is the significance of ALSA -71 and ALSA -18 messages at disconnect and how i can resolve this infinite loop . 3) is there any patch available in latest kernel which can be applied to resolve this problem . if back porting of any latest kernel audio class driver stack is done , which areas should be backported . Please find time to answer my queries .
