Ever since I've upgraded to Monterrey 12.4 from Big Sur, I have been experiencing the occasional Kernel Panic or black screen after the Apple logo on boot with a reference 6900 XT
This is the crash log:

Anyone experiencing anything similar to this and would spoorfing the W6900 XT Framebuffers help?
