7900 XTX memory clock gets stuck on lowest on Kernel 6.2

Brief summary of the problem:

Since updating my kernel to the Fedora 6.2 (6.2.2 / 6.2.3) (official koji build) i run into a persistent issue where my 7900 XTX suddenly locks up the memory frequency, as reported by radeontop, to ~100MHz while the Shader Clock is locked at 3.1 GHz.

Reverting to 6.1.15 immediately fixes this behaviour and the Card behaves as expected again.

This happens sometimes at boot, sometimes after a few hours. Most of the time it happened i managed to cause this by exiting a game (Borderlands 3, Proton-GE 7.{48,49,50}). This specific Game gets locked to ~30 FPS on the main screen when this issue occurs and performs much worse in game.
