** Description changed: DISCLAIMER: This is my second-ever bug report. Apologies in advance for any missing or inaccurate info. I am willing to troubleshoot and supply more/better info as needed. PROBLEM DESCRIPTION: After upgrading the kernel on my Ubuntu 22.04 Server test system from 5.15.0-18 to 5.15.0-22, I see absolutely no console output on my display past the grub menu. I can give the system a few seconds to finish booting, log in blindly and watch the activity LEDs on e.g. the network interface as i run a ping or similar. I can also log in remotely via SSH. So the system definitely does boot. But my display shows no output. ENVIRONMENT: (Output gathered via SSH while display was showing no output) testuser@testserver:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu Jammy Jellyfish (development branch) Release: 22.04 Codename: jammy testuser@testserver:~$ uname -a Linux testserver 5.15.0-22-generic #22-Ubuntu SMP Tue Feb 8 10:16:30 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux This was initially discovered on an Ubuntu Server VM running in EFI mode on VirtualBox 6.1.32. System was installed with the daily 'jammy-live-server-amd64.iso' image from 2022-03-07, fully upgraded as of 2022-03-10. Switching Graphics Controller in Virtualbox does not help, nor does 'nomodeset' or 'noacpi'. I am able to reproduce the issue on real hardware and with different physical graphics cards. Similar symptoms can also be observed in Ubuntu Desktop (still using EFI) by attempting to switch to tty with CTRL + ALT + F[3-6], or by taking note of the missing plymouth screen during boot. Systems installed/booted in legacy BIOS mode (both Server and Desktop) do not appear to be affected. I have tried reinstalling on both virtual and hardware platforms, with same result before and after upgrading the kernel. HOW TO REPRODUCE - Ubuntu Server: - Boot existing Ubuntu Server EFI installation with 5.15.0-18 and observe console output - Set GRUB_TIMEOUT_STYLE=menu and GRUB_TIMEOUT=10 in /etc/default/grub (to enable rollback) - Run update-grub - Run sudo apt full-upgrade and watch linux version 5.15.0-22 get installed - Reboot and observe your display (no console output will be shown after grub) HOW TO REPRODUCE - Ubuntu Desktop: - Download Ubuntu 22.04 Desktop daily ISO - Write ISO to USB - Boot from USB in EFI mode - Install system - Run sudo apt full-upgrade and upgrade linux* to kernel 5.15.0-22 - Reboot and observe missing plymouth screen during boot - Wait for graphical login screen to appear - Press CTRL + ALT + F[3-6] (screen will go black and/or freeze) - Press CTRL + ALT + F1 (screen will unfreeze and/or return to gdm greeter) WORKAROUNDS: If you still have 5.15.0-18 or earlier installed, select it in Grub. - OR install mainline kernel 5.16.11+ (for testing/recovery only). - OR boot/convert your system to boot in legacy BIOS mode. + and/or install mainline kernel 5.16.11+ (for testing only - will not work if you have Secure Boot enabled). + Alternatively, re-install/convert/boot your system to boot in legacy BIOS mode. --- ProblemType: Bug AlsaVersion: Advanced Linux Sound Architecture Driver Version k5.15.0-22-generic.
