Created attachment 111861 [details] GPU crash dump This is an Acer 4810TG laptop with both intel and radeon videocards, but the discrete one was (hopefully, as I was not using it) DynOff. I was doing nothing special: Konsole, Firefox, Google Chrome, Zathura running; I was about to launch Okular to print something, but I don’t remember whether I actually launched it when X restarted. I think I never had such an issue before upgrading the kernel (but also just recently I started using a second screen attached via VGA). dmesg: ~~~~ Jan 06 19:59:22 kirNote kernel: [drm] stuck on render ring Jan 06 19:59:22 kirNote kernel: [drm] GPU HANG: ecode 0:0xab0f77f9, in X [2708], reason: Ring hung, action: reset Jan 06 19:59:22 kirNote kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

It all looked fairly benign, then I realised it was gen4, where even a simple multi-vertex PRIMITIVE could crash. It looks like you have an old xf86-video-intel, could you please attach the Xorg.0.log? (Especially the Xorg.0.log.old after a hang + restart)
Created attachment 111870 [details] Initial X log
Created attachment 111871 [details] X log after restart Yes, xf86-video-intel is somewhat old, as is xorg-server itself: both are the latest stable on Gentoo.
Really old issue. Is this issue still seen with latest kernel?
No feedback in many months, closing. If issue still seen, please re-open.
