--- Comment #25 from barnoid@gmx.net --- I have observed this as well on a 5.15.32 kernel. The system is equipped with an AMD Threadripper 3970X and 2 x LG HDMI displays connected via DP (4K@60Hz). The error happens when powering-up the monitors after a long power-down period.

Ctrl-Alt-F1 and restarting X (i.e., the login manager) is sufficient to bring the system back into a useable state.
