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.

Is there a reason why it would not be created or could it be somewhere else?
Bug scrub: Hi Olivier, Could you try to reproduce it. Thanks
Created attachment 120138 [details] dmesg trace
I'm also having this issue, can help provide any other information required. It happens completely intermittantly with no trigger that I can pick up. Usually within 15-60min of boot. I'm currently passing these kernel params on boot: i915.preliminary_hw_support=1 drm.debug=0 drm.vblankoffdelay=1 i915.semaphores=0 i915.modeset=1 i915.use_mmio_flip=1 i915.powersave=1 i915.enable_ips=1 i915.disable_power_well=1 i915.enable_hangcheck=1 i915.enable_cmd_parser=1 i915.fastboot=0 i915.enable_ppgtt=1 i915.reset=0 i915.lvds_use_ssc=0 i915.enable_psr=0 Am now testing UXA accel method with Xorg to see if there's any improvement as someone stated on another site that it may help.
Confirmed setting UXA accel method works - however performance drops as expected to an almost unusable state. ------------------------------------------------------------ ~ » sudo cat /usr/share/X11/xorg.conf.d/20-intel.conf Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" EndSection ------------------------------------------------------------
Appears fixed running 4.4.0-rc4 kernel. Currently up to 4 hours without a lock-up.
Issue resolved running Kernel 4.4.0-rc4
So closed
