Tyrel,
The event pool used for queueing commands is destroyed fairly early in the ibmvscsi_remove() code path. Since, this happens prior to the call so scsi_remove_host() it is possible for further calls to queuecommand to be processed which manifest as a panic due to a NULL pointer dereference as seen here:
Applied to 5.1/scsi-fixes. Thanks! -- Martin K. Petersen Oracle Linux Engineering
