usb panic

[Matthew Dillon]

:Hi,
:
:Here's part of the trace from my usb panic. Happens during boot, when my flash stick is plugged in -

    There are a couple of delayed-timeout crashes that can occur with USB
    devices.  What happens is that the USB device schedules a delayed timeout
    on a related structue but then unexpectedly detaches and it's related
    structures are freed before the timeout occurs.

    Is there any chance you can get a crash dump?  It may not be possible
    due to being so early in the boot sequence.
