https://bugzilla.kernel.org/show_bug.cgi?id=211807 Daan (daandelombaert@xxxxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |daandelombaert@xxxxxxxxx --- Comment #14 from Daan (daandelombaert@xxxxxxxxx) --- I also had this in my logs yesterday, right before my system locked completely (had to do a hard reset). I also have a Lenovo Thinkpad Thunderbolt Dock, which connects my Thinkpad T480 with two external monitors (one Hdmi, one Displayport). I didn't have this lockup before, in the past both monitors were hdmi so maybe Displayport is the culprit here?
