Can you please attach the error state?

> Can you please attach the error state?

I only meet this issue once when run automation testing, I am unable to reproduce it. If meet again, I will update it.

It also happens once on HSW. Run 2 cycles on HSW, I am unable to reproduce it.

Assigning back to Ian since I am only focusing on BSW specific failures right now.

What's the PCI ID on the HSW machine?

Can you please try on the latest drm-intel-nightly.

id=0x0412, rev 06

I will test it on the latest drm-intel-nightly.

Test on BSW with latest drm-intel-nightly kernel, this issue still exists.

Please test current drm-intel-nightly, and if that fails, with http://patchwork.freedesktop.org/patch/39363 applied.

It's sporadically issue.  I will double check it. So update will be late.

It still happens on the latest -nightly kernel, IVB also has this issue.

I reproduce this error manually on HSW. Run ./bin/textureGather fs r 0 uint CubeArray repeat -auto -fbo 500 cycles. But no error stated collected in i915_error_state

[root@x-hsw24 lh]#  dmesg -r|egrep "<[1-4]>"|grep drm
<3>[  152.763646] [drm:i915_hangcheck_elapsed [i915]] *ERROR* Hangcheck timer elapsed... blitter ring idle


[root@x-hsw24 lh]# cat /sys/kernel/debug/dri/0/i915_error_state
no error state collected

Not reproduced on BSW-M and SKL-Y with fresh setup.

I will check on BYT-M/T.
Elio could you try with your NUC HSW and IVB?

This issue is not present with latest configuration on IVB, i will check it with HSW as soon as possible
