Hi.
So, current summary:
1) first patch + debug patch: I can reproduce the issue in wild, but not
with pm_test set;
2) first patch + debug patch + second patch: I cannot reproduce issue at
all, neither with "none", nor with "mq-deadline".
Thus, "blk-mq: align to legacy path for implementing blk_execute_rq" +
"blk-mq: add requests in the tail of hctx->dispatch" look like a proper
fix. Thanks for that!

If still relevant, here is a layout:
===
sda 8:0 0 8G 0 disk
|-sda1 8:1 0 128M 0 part /boot/EFI
`-sda2 8:2 0 7.9G 0 part
`-md0 9:0 0 7.9G 0 raid10
`-system-root 253:0 0 7.9G 0 lvm /
sdb 8:16 0 8G 0 disk
|-sdb1 8:17 0 128M 0 part
`-sdb2 8:18 0 7.9G 0 part
`-md0 9:0 0 7.9G 0 raid10
`-system-root 253:0 0 7.9G 0 lvm /
===
Anything else you'd like /me to test?
