Booting 4.3-rc1 or nightly on SKL-S results in

the firmware is there though, and of the latest version.

i915 loading at 1.139104 seems rather early, maybe you have i915 built-in but no firmware in initrd?

Comment 2 Timo Aaltonen 2015-09-17 07:38:18 UTC

yeah, turns out i915 is included in initrd in some cases, but not others.. I'll file a distro bug to include the fw too then.
