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!
