Hello,
I am currently experiencing boot problems. The problems occurred out of nowhere. Updates were already done before and the system was running smooth. I have not made any changes. I powered my laptop down and powered it back up since I have forgotten something and I got this message:
watchdog : BUG: soft lockup - CPU#2 stuck for 23s! [swapper/2:0]
The system is booting up fine after this message.
The error only shows up during cold boot (not via restart).
How can I debug this?Journalctl just showed me this output. But I am not able to pin down the problem.

I also do not use swap or have an unused swap partition.
