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.
