Systemd reboot halt Lenovo ThinkPad x230 running jammy

[Renato Botelho]

I've installed Ubuntu Desktop jammy on a Lenovo Thinkpad x230 laptop and upgraded all packages to latest version. When I try to reboot machine using command line reboot, shutdown -r now or using Restart option on desktop it just halts the laptop instead of reboot it.

I've downloaded klibc-utils package, which contains a reboot binary, and when I run it, laptop reboots just as expected.

I've collected strace output from both systemd and binary reboot calls (until SSH was dropped) and pasted at https://gist.github.com/rbgarga/b6a35e448a9c30502eaea09611191c73

Just let me know if you need any other information about my running system or hardware.

I forgot to add mandatory system details:

❯ lsb_release -rd
Description: Ubuntu 22.04.1 LTS
Release: 22.04

ii systemd-sysv 249.11-0ubuntu3.4 amd64 system and service manager - SysV links

Thanks for the strace output. Can you please also attach journal and dmesg output for a time range that captures this issue?

Well, it's really weird but I tried to reproduce the problem (what I see happening for at least 2 months) and for some unknown reason I couldn't. It's rebooting as expected using any of those methods.

I will try to investigate and understand what could be the change that fixed it but it's not worth it to keep this ticket open while I do it.

Thanks anyway!
