X freezes if the USB headphone is plugged

[Rami Al-Rfou']

If the headphone USB jack is plugged X crashes with segmentation fault and no login page or ttys are available. In case the headphone usb is not plugged, I can login, but the moment I plug, X crashes.

Please collect a full backtrace on this crash - see http://wiki.ubuntu.com/X/Backtracing for guidance.

Reading the instructions, now, I think X actually freezes it does not actually drop a login prompt. I have to wait till get another machine to ssh to mine while it is freezing.

There is a backtrace in the XorgLogOld.txt attached above and it is the one that freezes X.

[Rami Al-Rfou' (rmyeid)]

What it is missing till now?

it is not a crash, it just freezes. It does not drop a login prompt.

now, it stopped crashing because of the USB headset, however, it is hangs more often with this error thrown
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[88143.361495] [drm:kick_ring] *ERROR* Kicking stuck wait on render ring

[Mark Fodor (mfod)]

What made it stop crashing? I'm having the exact same problem... Is someone addressing this problem? Should I provide system or debug info to help move this forward? (desperate because I need USB headset for work)
