usb panic

["Todd T. Fries" <todd_(_at_)_fries_(_dot_)_net>]

This happens consistently when rebooting the machine after having a panic
that I couldn't address while I was in X.  So I did the 'boot sync' blindly
and every reboot until I power cycle the machine...

A normal dmesg (after powering down the machine and powring it back up it is
happy)...
