No problem.

Ok. Please test (when you have time) 6.1.55-1.
Also verify if it's also present in 6.1~rc3-1~exp1 to make sure it's present 
in the whole 6.1 series.
Use https://snapshot.debian.org/binary/linux-image-amd64/ to get it/them.

If the bug is NOT present in either the latest or the first, then try other 
versions till you find the last one that work and the first one that fails.

It was fixed in 6.3.7-1, so it was expected that a later versions also works.
But let's ignore bpo as it likely won't provide useful data points.

Unfortunately there isn't a 6.2 kernel uploaded to the Debian archive and thus 
not available on snapshot.d.o, but testing 6.3.1-1~exp1 should be useful.

I'd recommend to focus first on the 6.1 series for now.
If at a later point testing with 5.10 may be useful, we can do that then.
