I got the following oops after doing "modprobe uhci". The system froze
completely about 30 seconds after that.
Before that, I have unloaded uhci, loaded usb-uhci, and then unloaded
usb-uhci again. This could be relevant.
Please contact me if you need more information.

So if you just load the uhci driver everything works?
Did you have any usb devices connected?

Yes, I normally use uhci and do not have any problems. I might have had
a device connected (a bluetooth USB adapter), but I am not sure now.
Should I try to reproduce this, or is the trace sufficient?

Yes, try to reproduce this, then let the people at linux-usb-devel know
about it.
