I'm sorry, this is pissing me off. This is no way of handling a bug 
report....

Did you try to reproduce it *exactly* like withthe pwcx module? Because you

...which leads me to believe there's a race condition somewhere.

If there really is a problem with the pwcx module, that's important because 
a lot of people use that module. But I'm a bit skeptical since the pwcx 
module is really simple, and does nothing with the kernel except for a 
printk(). So it would be hard to trample over your system... 

Your Oops stacktrace points to somewhere in usbcore, and because you are 
unplugging the camera, it may be a simple dangling pointer in there...
