Ah, a notable difference between the hardware spec of the test servers and the real servers:
The test server is on a test machine which has a graphics board installed in it: EVGA e-GeForce 8400 GS Graphics Card - 512 MB RAM 512-P3-1301-KR The real servers are using the on-board Intel graphics. No option to move the Nvidia board to the impacted server machine as there is no PCI-e slot on the server boards. They have only one card slot which is in use for the RAID controller. -- 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: Confirmed 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. Hardware spec is an Intel Atom D945GCLF2D boxed motherboard with Intel Atom 330 Dual-Core processor and 2GB RAM. RAID is 3Ware SATA RAID.
