--- Comment #2 from Mika Kuoppala <mika.kuoppala at intel.com> ---
igt/tests/gem_workarounds --run-subtest=read
should have a mechanism in place to force context to get loaded before these
values are read.

Alternative is to try the patch attached.

The problem is that rc6 exit on bdw, is not enough to guarantee consistent
access to the context which these values are part of.
