Duplicate of bug 94539 ?
Comment 2 yann 2016-05-20 11:57:17 UTC 
I think bug 95469 is a duplicate (same root cause)
Comment 3 maria guadalupe 2016-05-27 15:17:03 UTC 
This is also reproduced on KBL with the next configuration

Comment 5 yann 2016-06-08 17:50:14 UTC 
Same root cause than bug 94539

*** This bug has been marked as a duplicate of bug 94539 ***
Comment 6 yann 2016-06-08 17:54:13 UTC 
root cause is linked to preparing or creating execbuffer (in i915_gem_execbuffer2 function located in i915_gem_execbuffer.c file), operation is called via ioctl from igt lib ioctl wrapper
