Bug ID: 106434 Summary: Graphical hangs, no keyboard, rest of system still active Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: koz.ross@retro-freedom.nz
Created attachment 139418 --> https://bugs.freedesktop.org/attachment.cgi?id=139418&action=edit 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.

--- Comment #3 from Koz Ross koz.ross@retro-freedom.nz --- Created attachment 139421 --> https://bugs.freedesktop.org/attachment.cgi?id=139421&action=edit 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).

--- Comment #4 from Alex Deucher alexdeucher@gmail.com --- Do you still have the issue without the CK patches?
https://bugs.freedesktop.org/show_bug.cgi?id=106434
--- Comment #5 from Koz Ross koz.ross@retro-freedom.nz --- 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.

--- Comment #6 from Jack Wolf jackwolf2454@gmail.com --- I have the same issue.
4.17.4 firmware 20180518 18.0.1 amdgpu
I also use displayport.
