Hello Jens,
With these two patches applied the scheduling-while-atomic complaint and
the oops are gone. However, some tasks get stuck. Is the console output
below enough to figure out what is going on or do you want me to bisect
this? I don't think that any requests got stuck since no pending requests
are shown in /sys/block/*/mq/*/{pending,*/rq_list}.
Thanks,
Bart.
