test ran with IGT_LOG_LEVEL=debug
When running igt@kms_frontbuffer_tracking@fbc-suspend on a i5-2450M with
today's drm-intel-nightly kernel, it fails at the following assertion:
(kms_frontbuffer_tracking:2392) CRITICAL: Failed assertion:
fbc_wait_for_compression()
Subtest fbc-suspend: FAIL (3.775s)
It is 100% reproducible on that machine, but on another another i7-2620M it
never triggers.
I am already running with the patch from <a class="bz_bug_link
