[Bug 570598] [NEW] Kernel oops caused while accessing one USB drive after a USB pen plugged in

[Alex Bennee]

Public bug reported:

Shortly after inserting a USB key into my hub the kernel oopsed on
accessing my other removable USB drive which I keep permanently
connected to my machine. It looks as though the addition of the key may
have caused by previously mounted drive to be re-registered on a new
device causing the confusion:
