stack traces during writing to disk. there is no way to kill the guilty process (kill -9).

blacklisting xhci_hcd and using ehci_hcd fixes the problem.

right now im unable to produce a stack trace since i blacklisted the module to use the HDD. i will do it tomorrow.

corruption on files written to this disk happened because of this. tried 3 different HDDs (one brand new).

All USB bugs should be sent to the linux-usb@vger.kernel.org mailing
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.
