OK, if this indeed passes then b6e68ee82585 ("blk-mq: Improve performance
of non-mq IO schedulers with multiple HW queues") might be what's causing
issues (although I don't know how yet...).

I can revert it from 5.12.0 and try. Let me know which next test is preferred :)

Let's try to revert this first so that we have it narrowed down what
started causing the issues.
