FWIW: That patch set was added to my kernel as well.

My LE box (Rock64) still needs updating to the 12.x series, but it's running 
LE 11.0.6 with kernel 6.1.74 ...
(FTR: I did my tests with a reasonably bare-bones Debian Trixie system)

You're comparing a (likely) heavily patched 5.x kernel to a (mostly vanilla?) 
6.10-rcX based kernel with a potentially completely different kernel config?
If so, I don't think you can draw that conclusion.
But it seems easy to verify by building a kernel with the same 6.10-rcX base, 
but without this patch set applied and do the same tests?

Feel free to contact me privately if you think I could help triaging, but I 
don't think we need to do that on-list.

Cheers,
