I logged on about ten minutes before taking the screenshot, and the failed to reinit gpu thread message was repeating at regular intervals; I too suspected that maybe my logging on would have somehow caused this so I observed it for a while to see, thinking that if this is the case then theoretically, the system should soon reboot; I was just surprised to see that it didn't and that nothing was logged/logging so I couldn't check when exactly it died initially either. :/

Mapping works correctly now with either --gpu-platform specified or not, the --no-adl was causing the mapping problem. Also, no more random sick/dead GPUs since said removal, hmh.

Seems to be in order now...
