I just got this oops by plugging in a 1.1 usb-storage device into a usb
2.0 hub plugged into a 2.0 controller. This is on 2.6.0-test2 + all the
usb patches I've applied:
Unable to handle kernel paging request at virtual address 20736cc5

Any thoughts?
I was trying to see if the error that I had been getting with
2.6.0-test1 when removing the same storage device. It was a repeating
message in the kernel log, no oops, but can't see that yet :)
thanks,
