Re: crash of usb ... backtrace included.

[Alexander Hoogerhuis]

I'm having similar oopses with bluetooth on my laptop (HP nc6000);
when "removing" the bluetooth from the USB bus (hotkey on laptop that
can disable it), or when shutting down and hotplug shuts down and
starts to remove modules, I get this one:

usb 3-1: USB disconnect, address 2
