I have the same issue on the following system: OS: Ubuntu 22.04 (updated from Ubuntu 21 on May 20th 2022) Kernel: Linux 5.15.0-30-generic, Linux 5.15.0-30-lowlatency Hardware: Lenovo Thinkpad Yoga 460 (20EM), Intel Core i7-6500U
Both poweroff and switching Ubuntu into standby lead into a state where the system doesn't react to any input in a useful way anymore. The hardware is still powered-on. Using poweroff, the power LED stays on and the keyboard still reacts to the key stroke combination for changing the keyboard backlight. When switching into standby (through Gnome, by shutting the lid, or by pressing the power button for half a second), the power LED begins blinking. This is normal behaviour when the systems gets powered off. But the blinking doesn't stop on its own, indicating that the system doesn't really poweroff. In both cases, booting the system up is not possible until it has been forced to poweroff by pressing the power-button for multiple seconds. Examining the systemd journal doesn't show any error. The journal ends with a message that the system will be shut down and that the journal ends at this point. So I have no clue, what's going wrong there. The problem only occurs with the 5.15 kernel versions mentioned above. If I boot Ubuntu with a 5.13 version, the shutdown works fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1964851 Title: Ubuntu 22.04 (dev-branch) shutdown/reboot hangs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1964851/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
