Today I managed to trigger some pretty bad faults with with v5.13-rc4 running on SM8150 (Snapdragon) and iozone. It seems the problem only happens when using bfq iosched, as I couldn't trigger it with mq-deadline.
Both the UFS driver and the BFQ scheduler have been changed significantly recently. It would help if this issue could be bisected. That will reveal whether the root cause is in the UFS driver or in the BFQ scheduler.
Thanks, Bart.
