System is BDWGT3e Mesa/DRM versions are tip of master test passes reliably on Linux 4.1 (stock debian testing kernel) Stock 4.3.0 kernel fails this test intermittently Test fails about 20% of the time, when run in Mesa CI (parallel execution, gbm back end). Sample output: /tmp/build_root/m64/lib/piglit/bin/arb_shader_image_load_store-qualifiers -auto -fbo piglit: debug: Requested an OpenGL 3.2 Core Context, and received a matching 3.3 context Probe value at (1, 0, 0, 0) Expected: 21.000000 Observed: 0.000000 Probe value at (12, 0, 0, 0) Expected: 1.000000 Observed: 0.000000 Let me know if more information is needed to reproduce this.
What's the failure rate when running the testcase standalone? (Confirming that it fails by itself would also be useful.)
Only BDWGT3e? Hmm, my GT3 is just an Iris 6100 not GT3e. That doesn't seem to be tripping up on -nightly.
BDWGT3e was the test machine I used. I can verify BDWGT2, I expect it to be the same. I have had terrible luck trying nightly in the past. Is it healthy ATM, or is there a known-good sha I can use? I will run it individually as you requested.
running by itself, it fails on BDWGT2 about 10% of the time. The subtest causing the failure is: PIGLIT: {"subtest": {"r16ui/permissive layout qualifiers/strict access qualifiers/permissive binding test" : "pass"}} Probe value at (1, 0, 0, 0) Expected: 21.000000 Observed: 0.000000

Mark, still an issue with latest kernels?
This bug does not reproduce on later kernels.
Thanks for the follow-up!
