Any suggestion what should be selected instead?

Do you have a patch against 4.13? I tried applying the following
patches from git format-patch ebb2c2437d8008d467969
	0001-blk-mq-only-run-hw-queues-for-blk-mq.patch
	0002-block-tracking-request-allocation-with-q_usage_count.patch
	0003-blk-mq-rename-blk_mq_-freeze-unfreeze-_queue.patch
	0004-blk-mq-rename-blk_mq_freeze_queue_wait-as-blk_freeze.patch
	0005-block-rename-.mq_freeze_wq-and-.mq_freeze_depth.patch
	0006-block-pass-flags-to-blk_queue_enter.patch
	0007-block-introduce-preempt-version-of-blk_-freeze-unfre.patch
	0008-block-allow-to-allocate-req-with-RQF_PREEMPT-when-qu.patch
	0009-SCSI-transport_spi-resume-a-quiesced-device.patch
	0010-SCSI-preempt-freeze-block-queue-when-SCSI-device-is-.patch
to current 4.13, but without success.
(I don't want to play with .14-pre kernels by now.)

Thanks a lot and all the best

Norbert
