Mark, why did you assign this to Ian if the kernel update made the failure happen? Ian gets bugs by default. If I know who to assign a bug to, then I assign it directly. Who are the candidates to get this bug?

Was mesa updated as well? Neil has pointed out that some of the ASTC patches may have caused these regressions. When I wrote this bug up, I was upgrading SKL kernels and attributed the failure to that change. However, now that I am testing SKL on a regular basis, I can see that these tests regressed in Mesa since 11.0. I bisected the test, and found that it regressed when ASTC was enabled for SKL: Author: Nanley Chery <nanley.g.chery@intel.com> AuthorDate: Tue May 19 12:28:20 2015 -0700 Commit: Nanley Chery <nanley.g.chery@intel.com> CommitDate: Mon Aug 31 17:29:36 2015 -0700 i965: advertise ASTC support for Skylake v2: remove OES ASTC extension reference.
