Tomasz, it looks like you were really close at resolving this regression
when you submitted the required patches for the 5.15.y branch a few
weeks ago:
https://lore.kernel.org/all/2023090417-silk-parting-36d8@gregkh/

What happened? Did you loose interest? Did you not understand what Greg
asked for? Do you need help?

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
