Awesome, thank you both for checking it out. So, it's definitely
something in my test environment.

Yeah, it could be. I've tested this on a rolling release (openSUSE TW),
so it's definitely quite different from Debian 10. It may take me a bit
to figure out what's going on, but I'll start with this kernel config and
report back any finding.

Again, thank you both for confirming it's working on your side.

Cheers,
