kernel:[ 7548.242662] watchdog: BUG: soft lockup - CPU#2 stuck for 3203s! [kauditd:110]

[Federico Foschini]

When updated to kernel 5.13.0-37-generic we get this error and the server became unresponsive.

I've updated four different servers and all have the same problem. On kernel 5.13.0-35-generic everything is fine

I've tested (accidentaly) on 4 different servers. Three of them have the same CPU of the bug report. The fourth one has the cpu attached to this comment.

I'm getting the same bug even on Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz, I'm starting to think it's not CPU related.

Am I the only one affected? Are there any logs which can help triage this bug?
