This looks like that same issue
https://bugzilla.redhat.com/show_bug.cgi?id=1767539
I don't think the BFQ fix has been sent to stable yet, or at least
it was not in 5.3.11
Any specific git commit id I should be picking up for this?
thanks,
greg k-h
Should be 478de3380c1c ("block, bfq: deschedule empty bfq_queues
not referred by any process") .
Thanks,
