I have built new desktop pc with haswell pentium g3420 and integrated graphics. I get often gpu hangs while web browsing with firefox. dmesg: [drm] stuck on render ring [drm] GPU HANG: ecode 0:0x87d3bffa, in kwin [1636], reason: Ring hung, action: reset [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. [drm] GPU crash dump saved to /sys/class/drm/card0/error This happens on Kubuntu 14.04 with kernel 3.18 (3.17 effected too) and latest drivers from intel graphics installer.
