panic: umass1: Unknown state 1

[Oliver Fromme]

I just got this panic on a recent stable/8 amd/64 system:
panic: umass1: Unknown state 1

Here's a screen shot from the KVM console:

Unfortunately, the crash dump that was written seems to be
lost.  A quick search on the PRs doesn't reveal anything
either ...  has anyone seen this type of panic before?

It happened when I was switching virtual remote drives in
the management application of an IBM blade center, i.e.
the USB drive is actually a virtual drive emulated by the
blade management system.  I did similar things a few times
before without a panic, so this isn't 100% reproducable.
Also, I'm reluctant to try again because this is a quite
important production server.

Best regards
   Oliver
