Kernel 6.2.x spams journal with repeating error every 5 seconds causing system lag and inability to power down, suspend or switch tty

Brief summary of the problem:

All versions of kernel 6.2 cause an error to be repeatedly spammed in journal which results in severely degraded system performance and inability to power down, suspend or switch tty. Upon boot, everything runs as expected. Once a heavier load is introduced, like starting a game, the system will start to flood my journal with

[drm:dc_dmub_srv_wait_for_inbox0_ack [amdgpu]] *ERROR* Error waiting for INBOX0 HW Lock Ack

endlessly until I am forced to hard reset. System operates as expected when reverting back to kernel 6.1.12.
