Created attachment 139421 [details] [review] My CK patches for the 4.17-rc kernel My mesa version is 18.1.0_rc3, libdrm-2.4.91, X.Org X Server 1.19.5. My kernel is 4.17-rc3, with the CK patches ported. I have attached the patch I applied to the kernel for completeness. I have disabled C-states in the BIOS, as well as ASLR and have rcu_nocb as a kernel parameter (due to Ryzen instability issues). Do you still have the issue without the CK patches? Yes, I do - I tried using a stock kernel, as well as a CK one which wasn't 4.17-rc3, and they all had this behaviour. I have the same issue. 4.17.4 firmware 20180518 18.0.1 amdgpu I also use displayport. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

Created attachment 139418 [details] Relevant fragment of dmesg when this occurs I sometimes (for seemingly no reason at all) have the graphics completely hang on my machine. I lose my keyboard as well, although my machine is still running (I can SSH into it and everything else still works). I can still move the mouse, but nothing visual responds (I can't click on anything, can't change active windows, etc). Some additional points of interest: - My DisplayPort monitor blacks out in such a case, while my DVI monitor keeps working (displaying the same still image) - Killing X or my WM has no effect on this once it occurs (only a restart fixes it) - I can't determine if any particular thing triggers it (seems totally arbitrary) I've attached a dmesg fragment from one such incident, as well as other pertinent information. Its mention of AMDGPU is why I reported this bug here.
