The reverse bisect reported commit 63a1281b651b8ebc04c829254c62bd6fbaf83eb0 as the fix. However, that commit is a dm merge:
commit 63a1281b651b8ebc04c829254c62bd6fbaf83eb0 Merge: 0a3f5af 9567366 Author: Linus Torvalds <torva...@linux-foundation.org> Date: Thu Apr 14 19:07:45 2016 -0700 Merge tag 'dm-4.6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm This indicates we went somewhere wrong in the bisect. We may need to now go back and test each commit again and ensure if the were good or bad. It might be first worth testing Xenial -proposed, since a few fixes just went in specifically for the XPS 15. Do you think you could test the -proposed repo? If so, see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1581005 Title: Dell XPS 15 9550 Freezes when HDMI is plugged in Status in linux package in Ubuntu: In Progress Status in linux source package in Xenial: In Progress Bug description: This is fixed upstream in the 4.6.0 series.
