Xorg.log
Previous dmesg is from 4.7.0, the attached one is from git HEAD. Using the _k_ firmware seems to make this happen much less frequently. I tried to reset the gpu by using /sys/kernel/debug/dri/0/amdgpu_gpu_reset, and the result is a NULL pointer dereference in the kernel. dmesg attached Created attachment 227901 [details]
Kernel Oops when resetting the GPU
This seems to be (very) related to https://bugzilla.kernel.org/show_bug.cgi?id=198883 |
The system is still operational, and I was able to login remotely via ssh. Seems to happen more often when the CPU is under load. Relevant dmesg: INFO: task Xorg:539 blocked for more than 120 seconds. Not tainted 4.7.0 #5 "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
