There isn't commit 988abd970566 in linux-6.0.y, so I guess the above
build must integrate other patches not in 6.0.y

From the source code in cki build[1], looks commit 80bd4a7aab4c ("blk-mq: move
the srcu_struct used for quiescing to the tagset") is included, but
commit 8537380bb988 ("blk-mq: skip non-mq queues in blk_mq_quiesce_queue")
is missed, that is why this panic is triggered.

BTW, if possible, I'd suggest to share kernel tree being tested in cki test
if non official kernel is tested.
