--- Comment #265 from Ortwin Glück (odi@....ch) ---
I think Jens pretty much summarized the situation in #245. To trigger the bug
blk-mq must be used together with an underlying block device (such as SCSI or
SATA) that is stateful after a rejected bio submit. Then it's just a matter of
enough concurrent I/O.

So a workaround is to just disable blk-mq with SCIS: scsi_mod.use_blk_mq=1
