This is interesting. This probably means that one or more threads got
stuck in __scsi_remove_device(). If you still have the crash dump
available it would be appreciated if you could verify whether this is
correct. If so, there might be an issue in the mpt2sas driver where
scsi_done() does not get invoked for all outstanding commands after a
surprise removal.
