Ok, since we keep running into this second bug, it would probably be better to bisect the Ubuntu kernels, versus the Upstream ones. There may be a fix in Ubuntu that prevents this second bug.
To do that, we also need to find the last good Ubuntu kenrel and the first bad one. The last 4.2 based kernel before a fork to 4.3 for Xenial was: 4.2.0-16.19 The first kernel based on v4.3-rc1 was: 4.3.0-0.9, so we should be able to bisect between those two. Can you first test the following two kernels and confirm 4.2.0-16.19 is good and 4.3.0-0.9 is bad. 4.2.0-16.19: https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/ppa/+build/8287818 4.3.0-0.9: https://launchpad.net/ubuntu/+source/linux/4.3.0-0.9/+build/8360668 NOTE: With both these kernels, you have to install both the linux-image and linux-image-extra .deb packages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1609242 Title: Kernels 4.3-4.8 result in blackscreen - Intel Ivybridge To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1609242/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
