Well I think that usbmon is probably at fault here for trusting
drivers too much and not doing any sanity checking.  But I can try
removing the uvcvideo driver and seeing if I can get the system to
crash then.

I was busy last night and didn't have a chance to even touch the
system.  Hopefully more time tonight, but I'm not sure.

Thanks for the hints, I'll give them a whirl.
