You have been subscribed to a public bug by Jan Groenewald (jan-aims):

When I remove the USb headset (C-Media USB Audio Device) I get a system panic and the system freezes. 
It only happens sometimes, I cannot figure if this is related with some software that I am running at the time, maybe a youtube player. I do have an image of the event (http://www.flickr.com/photos/valugi/8410365819/sizes/k/in/photostream/) and the output of lsusb -v > lsusb-v.log.

I am available for further tests if you need any.
Best regards
Valugi
