Can you also confirm the bug does indeed happen with the upstream 4.4 final kernel: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/
That will tell us if the bug was introduced in 4.4 or one of the 4.4 stable updates. It will also tell us that 4.4 final is the starting kernel for the reverse bisect. We should also narrow down the 4.5 a bit further as well by testing some of the 4.5 release candidates. Can you test 4.5-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-rc1-wily/ -- 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/1656605 Title: No server console display after Grub screen until fully booted and pressing Ctrl-Alt-F1/8 Status in linux package in Ubuntu: In Progress Status in linux source package in Xenial: In Progress Bug description: Today I did our first production 14.04 to 16.04 LTS server upgrade. I had done so a couple of times successfully on test server machines. Upon booting up on the 16.04 system/kernel, after the Grub screen the server console screen is completely blank. Someone suggested using Ctrl-Alt-F1/8, and indeed pressing those hotkeys does toggle through the tty screens. There is no boot process logged to the server console screen. I did have the last 14.04 kernel yet installed, so selected that one from the Grub menu. Booting that 14.04 kernel, then server console display behaves normally. So I suspected perhaps a bum install of the 16.04 kernel. I used the following commands while booted to the 14.04 kernel to reinstall the 16.04 kernel: $ sudo dpkg -P linux-image-4.4.0-59-generic linux-image-extra-4.4.0-59-generic linux-image-generic $ sudo apt-get install linux-image-generic Same results booting the 16.04 kernel after those steps.
