Yes, it wont boot. There is no testcase as I don't even make it to a
boot prompt. I applied the patch and it crashes, I remove the patch and
it boots without issue.

Attached is the full dmesg and the config used. I applied it to

ae97a0ba0197fb424008a317b79bebacd6a50213
Linux 4.19.56-rt23

It works fine for 5.0.14-rt9 where it was added.
