Seems like there's a problem outside of i915. No, this is memory corruption caused by i915. *** Bug 88685 has been marked as a duplicate of this bug. *** I test on drm-intel-nightly kernel(98592c_20150122) with i915.enable_execlists=0, it works well. Test on the latest drm-intel-nightly(8b4216_20150203) kernel, it takes more than 10 minutes and doesn't exit testing, I guess it has a new regression, We will file a new bug to this this on the latest drm-intel-nightly kernel.
