Hmm.. I still cannot repro the hang in my test. I have:

^^^^^^^^^^^^^^ all works fine.
Did I miss something?
No :(
I am currently not testing against the mdraid but this shouldn't matter.
However, it looks like you don't test on bare metal, do you?
I tried to test on VMware Workstation 16 myself but VMware's nvme
