Can you try "dm_mod.use_blk_mq=0 scsi_mod.use_blk_mq=0" as well?
Block multiqueue was enabled in debian's 4.17
(https://salsa.debian.org/kernel-team/linux/commit/049487d8822c141bef503b024e73db55e2a695ff)
but there's no support for runtime power management yet:
https://github.com/torvalds/linux/blob/a26fb01c2879ed7026e6cbd78bb701912d249eef/block/blk-core.c#L3765
Unfortunately, the above code doesn't prevent laptop-mode-tools, tlp nor
custom udev rules from enabling runtime-pm for devices so if you use any of
that, you might be having runtime-pm enabled on devices that don't support it,
and therefore get hangs.
See https://github.com/rickysarraf/laptop-mode-tools/issues/123 for more
details.
