Hiya

I did some testing myself recently and unfortunately doing 20 tests was not
enough for me. I found that it could be 50 - 100 resumes before it would fail
so I capped mine at 150 resumes, there were too many times where things looked
fine for me with less than 50. After I tested kernels between 5.10.4 to
5.11-rc5 ( I didn't use 5.10.0 to 5.10.3 ) and found that this commit

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=a10aad137326d137a969fc6cc3555992b99ff9fc

was causing the issue for me
