The same problem also triggered with SAS device according to Dan. There was a lot of debugging on this a few weeks back and Alan Stern posted a SCSI layer patch that fixed the problem (for both USB and SAS): http://68.183.106.108/lists/linux-usb/msg49001.html But for some reason that patch didn't make it into 3.0 and 3.0 still happily oopses as the RC*s. Can you please merge this patch ASAP? This should also go to stable. At least for me it makes pure 3.0 very risky to use, because these USB hotunplug events are not uncommon and I end up with a dead machine.
