Upgrading to 5.2 (from 5.1.y) on a "Dell XPS 13 9350" (is that a skylake too?) showed similar symptoms. There's no pattern to the freezes that I can see. They're rather frequent too (think every few minutes). Eg, two freezes while composing this message! My totally silly workaround is suspending (via Fn + Insert) and resuming. Did you manage to narrow this any further? Thanks, Paul Bolle
