Kernel loses USB-drive

[Fridtjof Busse]

Binary package hint: linux-image-generic

I have a serious problem with my backup-drive (using dar): The kernel reproducable loses contact to the drive on feisty. Works just fine on edgy, and I tested it with two different drives, it happens every time.
I have to reboot the system to be able to use the drive again (though no fsck was necessary so far after the hang).

After the last bunch of updates, the problem vanished, i.e. I can't reproduce it anymore. Don't know what fixed it, but it seems to work now :)
