Created attachment 121518 [details] bzip'd /sys/class/drm/card0/error On a Skylake system (i5-6260U, Intel NUC6i5SYH) I'm getting multiple GPU crashes up to the point of complete system freeze. This reproduces easily when opening a browser with WebGL-intensive processes, and happens within 10-20 seconds. Running x86_64 Arch Linux, kernel 4.4.1. Tested with 4.5-rc2 and same problem occurs there as well. Error log attached.
Currently I'm using this workaround which disables most of the hardware acceleration $ cat /etc/X11/xorg.conf.d/20-intel.conf Section "Device" Identifier "Intel Graphics" Driver "intel" Option "DRI" "false" EndSection
Booting with kernel param i915.enable_rc6=0 seems to workaround this bug.

Also attaching my current mesa version: $ pacman -Q mesa mesa 11.1.2-1
INSTDONE says VS is hung, but the EUs are all done. Would be nice if we had that patch I wrote to dump all the INSTDONE bits for multislice parts, as this is a GT3.... Imre? The batch contents leading up to the hang looks okay to me. It's not even doing anything complicated, just a single rectangle (rectlist).
Same issue for me with exactly the same device on a linux kernel 4.4.1. The workaround works well doing i915.enable_rc6=0 on kernel param do the job. The xorg.conf is not needed.

There were workarounds on SKL pushed in kernel, so please re-test with latest kernel to see if it has some benefits on that work.
