Was running chromium-browser [37.0.2062.94-0ubuntu0.14.04.1~pkg1042], opened a lightweight website in a new tab, mouse cursor stopped moving (but visibly changed with mouse movement for a little bit, until it then completely froze). [11385.804027] [drm] stuck on render ring [11385.804034] [drm] GPU crash dump saved to /sys/class/drm/card0/error [11385.804036] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [11385.804037] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [11385.804038] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [11385.804040] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. [11385.806495] [drm:i915_set_reset_status] *ERROR* render ring hung inside bo (0x9ad6000 ctx 0) at 0x9ad77a0 [11386.312025] [drm:i915_reset] *ERROR* Failed to reset chip.

Interesting. I had not noticed any crashes like this before, but it is consistently happening when I direct chromium at https://ello.co/beta-public-profiles and attempt to hit 'login'. Additional output this time: [ 435.806361] [drm:i915_set_reset_status] *ERROR* render ring hung inside bo (0xfe3b000 ctx 0) at 0xfe3c9e0 [ 435.864015] [drm] GMBUS [i915 gmbus vga] timed out, falling back to bit banging on pin 2 [ 436.312016] [drm:i915_reset] *ERROR* Failed to reset chip.
