https://bugzilla.kernel.org/show_bug.cgi?id=206475 --- Comment #14 from Andrew Ammerlaan (andrewammerlaan@xxxxxxxxxx) --- I sort of worked around this too. I changed two things: 1) the iGPU is now the primary GPU, and I use DRI_PRIME=1 to offload to the AMD gpu. This has reduced the amount of things that are rendered on the AMD card. This didn't actually fix anything, but it did remove the necessity for a hard reboot when the AMD GPU does a reset. Now, when the GPU resets only the applications that are rendered on the AMD card stop working, the desktop and stuff stay functional. 2) I added three fans to my PC. Though the card's thermal sensor never reported that it reached the critical temperature (it went up to 82 Celsius max, critical is 91 Celsius). There definitely does seem to be a correlation between high temperatures and the occurrence of the resets. And more fans is always better anyway. I still experienced some resets after switching the primary GPU to the iGPU, but only if I really pushed it to it's limits. I haven't had a single reset since I added the fans. (Though admittedly I haven't run a decent stress test yet, so it is still too early to conclude that the problem is completely gone) Since under-clocking the card worked for you, and adding fans seems to work for me. I have a hunch that even though the thermal sensor doesn't report problematic temperatures some parts of the card actually do reach problematic temperatures nonetheless, which might causes issues leading to a reset. I'm not sure where the sensor is physically located, but considering that the card is quite large, it doesn't seem that far fetched to me that there could be quite a large difference in temperature between two points on the card. Perhaps this card could benefit from a second thermal sensor or earlier and/or more aggressive thermal throttling. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
