Below is an example from my syslog. I just realised that this is a slightly different "GPU hung" message, but the result is the same for me.

This one coincided with one of the complete lock-ups, that could only be resolved by Alt +SysRq-REISUB. I will now try the approach proposed in Comment #81, hoping for the best. I hope that I am not seeing two different issues here. The GPU hang-up error message has been reoccurring without obvious hang-ups in the past few days, while my complete hang-ups have been happening randomly, sometimes with the possibility to reboot as outlined above, sometimes without (only the power button would do) and sometimes the computer turned itself off without any interaction from my side, and without leaving any trace of a crash in the log files...
