Could you give a try to the following:

With this patch, I run 10 time about gem_concurrent_blit, didn't reproduce this issue.

Because of this bug, QA disabled 131 IGT cases.

It also happenes on SKL.

add SNB in this issue.

@Imre Deak 

On 2014-11-20, QA tested your patch, the result shows positive, will you plan to merge up your patch? Thanks.

It's been merged since a long time:

commit 2837ac40698d0931727b957a40c8c8ea27c3bcb2
Author: Imre Deak <imre.deak@intel.com>
Date:   Wed Nov 19 16:25:38 2014 +0200

    drm/i915: vlv: increase timeout when setting idle GPU freq

But this will only work for byt, so you need to file a new bug for snb/skl.

Tested gem_concurrent_blit on SNG and BYT with the latest nightly kernel and latest igt . All subcases successfully pass.
I will test the gem_evict_everything case next week.

Tested gem_evict_everything on BYT with the latest nightly kernel and latest igt.
