Package: linux-image-2.6.23-1-amd64
Version: 2.6.23-2
Severity: important

*** Please type your report below this line ***

I seem to have run into some sort of io kernel bug.  I connected a usb drive
(trekstor datastation pocket x.u), mounted a partition, juggled data around
(tens of GB), and umounted it.  When i removed the drive from the usb port,
I ran into a kernel bug.  I have used this disk and enclosure combo with this
machine and kernel before without any problem, also shuffling lots of data,
though maybe not quite as much.  An e2fsck on the mounted partition turned
up no errors.


Here is the relevant part of the dmesg output:
