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
