Can you please reply with the relevant bugzillas? Since about 2 months
QA is supposed to be using the piglit runner for their framework, so
any difference in test results compared to what piglit would report is
fail.

Note though that the piglit timeout support was busted by some
refactoring from Dylan Baker, Thomas has patches to fix that again.
But if this is indeed a failure from QA then I'll escalate this like
mad.

The plan is to have a server with piglit jsons of latest -nightly for
the full set of machines. QA hasn't yet delivered that though ...
