Occasionally, this piglit test fails on haswell with the following signature:

/tmp/build_root/m32/lib/piglit/bin/arb_sync-ClientWaitSync-timeout -auto -fbo
glClientWaitSync returned GL_CONDITION_SATISFIED.

glClientWaitSync returned GL_CONDITION_SATISFIED.
glClientWaitSync returned GL_CONDITION_SATISFIED.
glClientWaitSync returned GL_ALREADY_SIGNALED.

It also fails reliably on byt and g965.
Comment 1 Chris Wilson 2015-09-23 10:20:33 UTC 
Kernel?
Comment 2 Mark Janes 2015-09-23 15:39:05 UTC 
kernel is 4.2.0
Comment 3 Ben Widawsky 2015-10-07 23:18:55 UTC 
I've reproduced this on Broadwell.
Comment 4 Mark Janes 2015-10-07 23:19:53 UTC 
I withdraw the comment about g965/byt.  I can not reproduce failures on those platforms.

The test fails once in several thousand runs.
Comment 5 Mark Janes 2015-10-07 23:25:24 UTC 
my mistake, the test does fail on BYT/g965.  I was looking for intermittent results from those platforms.
Comment 6 Mark Janes 2015-10-07 23:29:33 UTC 
byt/g965 were fixed by 10c82c6c5fc415d323a5e9c6acdc6a4c85d6b712 for newer kernels.
Comment 7 Ben Widawsky 2015-10-28 14:48:20 UTC

Comment 8 Denis 2018-11-22 13:47:55 UTC 
looks like issue was fixed long time ago but wasn't closed

https://mesa-ci.01.org/mesa_master_daily/builds/4602/group/46728281c59ff6822e4cfcd51542697b

current runs show that test passes ok
Comment 9 Paul 2019-03-12 09:56:13 UTC 
I've run test on Broadwell (Intel® HD Graphics 5500) with Ubuntu 18.04 and Kernel 5.0.1, Mesa 18.2.2 and latest master version (19.1.0).
Test successfully passed.
