[Kernel-packages] [Bug 1989521] Re: Ubuntu 22.04.1 CPU soft lockup occurs repeatedly
Can confirm happening to my reasonably new installation on server 22.04.3. Server isn't doing much, some dockers and a tp-link omada installation. Have null'd out the suspend options. Is anyone else also runing plex, after the soft lockup goes on for long enough I start getting these in my kern log. kern.log.1:Oct 18 03:43:24 nas kernel: [79118.116772] watchdog: BUG: soft lockup - CPU#8 stuck for 50271s!

[Kernel-packages] [Bug 1989521] Re: Ubuntu 22.04.1 CPU soft lockup occurs repeatedly
I troubleshooted some more, and it looks like I may have resolved the issue. For an unknown reason, suspend/hibernation service was enabled on this server. It looked similar to this issue here https://bbs.archlinux.org/viewtopic.php?id=269203, where a race condition causes CPUs to freeze upon resuming from a suspend state. I disabled suspend services and I have not seen another occurrence of the issue yet. $ sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target hybrid-sleep.target Created symlink /etc/systemd/system/sleep.target → /dev/null. Created symlink /etc/systemd/system/suspend.target → /dev/null. Created symlink /etc/systemd/system/hibernate.target → /dev/null.
