We have already worked on "wait_event" usage in "megasas_issue_blocked_cmd".
That code will be posted by LSI once we received test result from LSI Q/A team.
If you see the current OCR code in Linux Driver we do "re-send the IOCTL
command".

The simscsi driver processes the requests in the request routine and then
offloads the completion callback to a tasklet. This is buggy because there
is parallel unsynchronized access to the completion queue from the request
routine and from the tasklet.
With current SCSI architecture, requests can
Hi list,
When a tape device is reserved with old reserve/release commands,
we see inquiry only works on the scsi generic device. For scsi tape devices
open() fails already:

When the controller encounters an error (including QUEUE FULL or BUSY
status), it aborts all not yet submitted requests in the function
sym_dequeue_from_squeue.
This function aborts them with DID_SOFT_ERROR.
If the disk has a full tag queue, the request that caused the overflow is
aborted with

Whoaa!!
I recompiled the master again, but now with a little bit modified
configuration, mainly I disabled the CONFIG_USB_STORAGE_CYPRESS_ATACB and
it works like a charm! Disk is properly and immediately detected and works!
I also tried to boot to standard kernel and disable loading ums_cypress
