--- Comment #3 from Kenneth Graunke <kenneth at whitecape.org> ---
I can confirm Clayton's report, and bisected it way back to the 4.11-rc1
timeframe:

b7048ea12fbb2724ee0cd30752d4fac43cab0651 is the first bad commit

    drm/i915: Do .init_clock_gating() earlier to avoid it clobbering watermarks

To reproduce, do:
$ while true; do ./glcts -n ES2-CTS.functional.fragment_ops.blend.*; done |&
grep Fail
in 3-4 terminals simultaneously.  Failures should show up very quickly.

FWIW, this is using the teamforge CTS repo, 'updated-cts' branch, built with
DEQP_TARGET=x11.  (It's old, we're in the process of updating to the modern ES
CTS, but not quite there yet...)
