f14-os8, xo-1.5 kernel trace

[Martin Langhoff]

Hi Daniel, list

I have a mangled bug report. Was running yum -ty install patch over a
WEP-encrypted AP, and plugged a usb flash disk, when I got dumped this
kernel trace.

Not sure which subsystem it is. A few minutes after after, the unit
lost keyboard input, which seems to be happening quite a bit under
f14.
