Panic with external hard drive

[Christian Brueffer]

Hi,

when I plug my external disk in via USB 2.0 and power it up afterwards
I get the following panic.  When I power it up first and plug it in
afterwards, everything works.

The machine runs a 7.0-CURRENT from today.

Dump and debug kernel are available for further debugging.
