A friend advised me to check two more outputs between a 14.04 server and 16.04 impacted server. Attaching the following additional outputs:
mdlueck@ldslnx01:/srv/shares/data/Download/OpenSource/Ubuntu/Xenial/Bugs/1656605_ServerNoConsoleDisplay$ cat /proc/consoles > consoles.log mdlueck@ldslnx01:/srv/shares/data/Download/OpenSource/Ubuntu/Xenial/Bugs/1656605_ServerNoConsoleDisplay$ cat /proc/cmdline > cmdline.log mdlueck@ldslnx01:/srv/shares/data/Download/OpenSource/Ubuntu/Xenial/Bugs/1656605_ServerNoConsoleDisplay$ cat consoles.log tty0 -WU (EC p ) 4:1 mdlueck@ldslnx01:/srv/shares/data/Download/OpenSource/Ubuntu/Xenial/Bugs/1656605_ServerNoConsoleDisplay$ cat cmdline.log BOOT_IMAGE=/vmlinuz-4.4.0-59-generic root=UUID=87ad7999-94fd-4004-b898-d6a943e5895e ro quiet splash vt.handoff=7 BTW: Another server, same config still on 14.04 LTS shows output: mdlueck@cirlnx01:~$ cat /proc/consoles tty0 -WU (EC p ) 4:1 $ cat /proc/cmdline BOOT_IMAGE=/vmlinuz-3.13.0-107-generic root=UUID=b8d89557-1fb2-4748-8708-f6ca416b7a87 ro quiet splash vt.handoff=7 So looks quite similar output. (I do not detect any red flags, at least.) ** Attachment added: "consoles.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1656605/+attachment/4804628/+files/consoles.log -- 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.
