The internet is full of forums and blogs and whatnot telling you to set all
kinds of i915 options for various reasons. Don't do it. Remove these as well:

Sep 12 01:36:26 nanook kernel: [    1.251643] Setting dangerous option
enable_guc - tainting kernel
Sep 12 01:36:26 nanook kernel: [    1.252444] Setting dangerous option
enable_dc - tainting kernel
Sep 12 01:36:26 nanook kernel: [    1.253254] i915: unknown parameter
'enable_rc6' ignored

Please *do* set the drm.debug=14 option, reboot and redo the logs. We're not
getting any debug messages in the logs. Note that it's a drm option, not i915.
