Comment # 18
on bug 104064
from taijian@posteo.de
Adding to the above comment after some further testing: I rebuild earlier today with HEAD at c2637e788da7. Startup went well, error messages were as before. I then launched Steam, which seemed to power up the dGPU for a short time, before it turned off again. So far, so good. I the started a gaming session, using the dGPU. Performance was about even with 4.16rc3 without dc. There were some artifacts/stuttering when scrolling, but I read on Phoronix that dc likely works best with mesa 18.0/LLVM6, which are not out yet. So nothing really worrying. However, when I quit the game and wanted to do another dmesg dump to look at and upload here, the computer froze again and became completely unresponsive before I could get to that. So it seems that the problem is not with the dGPU powering up for the second time, but with it powering down for the second time in a session. Any ideas why that might be or what kinds of test I could do to help narrow this down?
