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 at 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.
