USB OOPS 2.6.12

[Wakko Warner <wakko@animx.eu.org>]

I plugged in a USB 2.0 external hard disk (ION) and the usb controller
apparently could not power the device (wouldn't spin up, the device itself
works on other machines).  I unplug the drive and I received an OOPS.

DMESG:
usb 4-5: new high speed USB device using ehci_hcd and address 6
scsi5 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 6
usb-storage: waiting for device to settle before scanning

I guess I don't have symbols turned on, so here's the same thing from syslog:
