Yes, almost. What about khubd hanging when machine is shutdown?

Hi Jens,
may I point you at this problem report:
http://thread.gmane.org/gmane.linux.kernel/1420814
It is surely a misconfiguration on my part (the used io scheduler
configured as a module), but the behavior is somewhat problematic
anyway: at least in this case USB storage is essentially locked up.
Regards,
Alex
