However - from the bit of research I've done trying to figure this problem out for myself I believe the following explains the overheating and burst of fan speed instead of proper cooling behavior. Here is my sensors bit from kernel 4.18.x - I have the R9-290. amdgpu-pci-0100 Adapter: PCI adapter vddgfx: N/A fan1: 0 RPM temp1: +65.0°C (crit = +120.0°C, hyst = +90.0°C) Take note that this displays the proper critical and hysteresis values for my card. If you look at the post on comment 14 which is how sensors display the crit/hyst value for kernels beyond 4.18.x you notice the critical value is about 19x the temperature of the surface of the sun and the hyst value is absolute zero. These values are hard coded into kernel source code in some file, forgive me as I do not recall where I saw the code snippet. But I strongly believe that correcting the values in the file or changing it to detect proper crit/hyst values based on card will correct this issue. I simply do not have the means to do this, nor do I know how to submit kernel bug fixes and hope someone with more experience could give it a shot and see if the resulting kernel functions properly. -- 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
