[Bug 98706] Kernel loses USB-drive

[Fridtjof Busse]

Public bug reported:

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).
