--- Comment #239 from Marc Burkhardt (marc@...nowledge.org) ---
Could anyone just sum up what needs to be set to trigger the bug (as of the
understanding we have now)?

I use

scsi_mod.use_blk_mq=y

and

dm_mod.use_blk_mq=y

for ages but I do not see the bug. I use the

mq-deadline

scheduler.

#232 somehow suggests it needs additional memory pressure to trigger it,
doesn't it?

Quite confused here...
