Comment 2 Jani Nikula 2015-11-17 15:48:21 UTC

Nothing in the test ensures that the panel, and therefore the backlight, is enabled during the test. Pretty sure this is test failure. Needs fixing nonetheless.

Comment 3 Jani Nikula 2015-11-18 12:55:52 UTC

Please run the test with this igt patch, and post the igt logs and dmesg again:
