Are you sure you have linux-image-extra installed on the Kabylake system ? I installed on a non-i915 system and was able to modprobe the i915_bpo module without encountering any missing symbols. I am going to hold off on this pull request until you are a little more sure of your bits. rtg

Yeah, I figured it out.. the KBL system had linux-signed-image of the same abi version installed and that conflicted with the local kernel image build, so I purged linux-signed-* and it works fine now. so I think it's fine to merge now :)
BugLink: http://bugs.launchpad.net/bugs/1560395 Hi This branch would update i915_bpo from an upstream prerelease tag to what will be in 4.6-rc1. The caveat is that while the module loads and works fine on Skylake, it fails on Kabylake with i915_bpo: Unknown symbol pm_runtime_get_if_in_use (err 0) and I've no idea why, since the commit to add that symbol is included and the kernel should have that.. but I've sent this anyway in case someone has better ideas on why it fails here... -- The following changes since commit 3045e95c430122aff2e6c0c9ae650e812e4117c3: UBUNTU: Ubuntu-4.4.0-15.31 (2016-03-18 12:49:37 -0600) are available in the git repository at: https://git.launchpad.net/~tjaalton/ubuntu/+source/linux/+git/xenial i915-bpo for you to fetch changes up to 885ec0587d39584356e5040eef275a97daeb7f30: drm/atomic-helper: Implement subsystem-level suspend/resume (2016-03-24 12:19:30 +0200) ---------------------------------------------------------------- Maarten Lankhorst (1): drm/core: Add drm_for_each_encoder_mask, v2.
