Comment 1 Martin Peres 2017-10-19 10:17:03 UTC
Increasing the priority because it is only seen on GLK.
Comment 2 Maarten Lankhorst 2017-10-19 11:16:26 UTC
Test failure, not a GLK failure. :)

std_1024_mode was allocated on the stack, which was overwritten by garbage. This only happened when no fallback modes were available. This is only the case on eDP, because it has a single mode only.

Fix:
