--- Comment #11 from Damian Nowak nowaker@geozone.pl --- Just for the record - Mesa 17.1.4-1 and Linux 4.11.9-1-ARCH stalled on me today. But I know the next time it'll stall again will be a different Mesa & Linux version as I've been using Mesa 17.1.x and Linux 4.11.x for more than a month and it's the first time it's happened.
