Finished my bisect: 7bb4014e065abf88c1698bc5fde7a91caf907265 is the first bad commit commit 7bb4014e065abf88c1698bc5fde7a91caf907265 Author: Rob Clark <robdcl...@gmail.com> Date: Mon Jan 25 18:06:48 2016 -0500
drm/radeon: only init fbdev if we have connectors BugLink: http://bugs.launchpad.net/bugs/1546572 This fixes an issue that was noticed on an optimus/prime laptop with a kernel that was old enough to not support the integrated intel gfx (which was driving all the outputs), but did have support for the discrete radeon gpu. The end result was not falling back to VESA and leaving the user with a black screen. (Plus it is kind of silly to create an framebuffer device if there are no outputs hooked up to the gpu.)
