OK. Just tried to run 4.3rc1. It's broken. What I noticed in 4.2.8 (it works though) for the first time was this error at start-up: kernel: [1.606885] Console: switching to colour frame buffer device 170x48 Aug 11 15:08:30 Zbox kernel: [1.611424] i915 :00:02.0: fb0: inteldrmfb

4.2.8 was successful. For the 4.3 unstable versions I installed linux-4.3.0-040300rc4-generic - It's broken like the 4.4-8 Kernels. Unfortunately I will have to stop testing for now. Adding all the kernels broke my system :/ I'll need to clean that up before I continue. -- You received this

Ugh... that was painful testing :) All Kernels 4.3-4.4.x are broken. I've been using 14.04 for two years now. Does this mean I'll need to go through every Kernel between the releases? I'll download the Kernel for 15.04 now. Hopefully it'll work. -- You received this bug notification because

I'd like to perform a kernel bisect to figure out which commit caused this regression. We need to identify the earliest kernel that did not exhibit the bug and the first kernel that did exhibit the bug. Can you test the following kernels and post back? v4.4 final:

Unfortunately, it's the same behavior. As with all other 4.x kernels, I see the following errors when installing the deb packages: update-initramfs: Generating /boot/initrd.img-4.8.0-040800rc1-generic W: Possible missing firmware /lib/firmware/i915/kbl_dmc_ver1.bin for module i915 W: Possible

Can you also give the 4.8-rc1 kernel a try? If it still exhibits the bug, we can perform a kernel bisect. 4.8-rc1 can be downloaded from: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8-rc1/ ** Tags added: needs-bisect -- You received this bug notification because you are a member of
