Dear Maintainer,
today kernel 6.4.4 entered testing and with this kernel the performance in
games for me is extremely low. I tested supraland, witcher 3 and d2r and get
less than 20 fps in all three games with my AMD RX 6600. If I boot kernel 6.3.7
everything is fine again and I get 60+ fps in those games.

Regards
Axel

Further investigation shows mclk is stuck at lowest frequency so it is
most likely the same bug as reported here:
