Intel Skylake graphics hangs randomly but seems to happen faster while running
minecraft, i presume because the graphics is being heavily used. The whole
system becomes is unresponsive. This happens on all 3 of my skylake systems (2
laptops and 1 desktop).

Nov 09 03:02:05 laptop kernel: [drm] stuck on render ring
Nov 09 03:02:05 laptop kernel: [drm] GPU HANG: ecode 9:0:0x84df9ffc, in java
[2403], reason: Ring hung, action: reset
Nov 09 03:02:05 laptop kernel: [drm] GPU hangs can indicate a bug anywhere in
the entire gfx stack, including userspace.
Nov 09 03:02:05 laptop kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
Nov 09 03:02:05 laptop kernel: [drm] drm/i915 developers can then reassign to
the right component if it's not a kernel issue.
Nov 09 03:02:05 laptop kernel: [drm] The gpu crash dump is required to analyze
gpu hangs, so please always attach it.
