I have exactly the same issue with a NUC11PAKi7. Do you have an update on your issue?

It could be related to this issue: https://community.intel.com/t5/Processors/Frequent-crashes-on-i5-11500/td-p/1280709 The BIOS is up-to-date, as is the intel microcode package. It doesn't seem to matter which kernel I use. I'm using the OEM one since the regular kernels for 20.04.3 (a) also have this problem, and (b) have broken IR support (https://askubuntu.com/questions/1380500/kernel-rc- rc0-receive-overflow).

Let me know how else I can help.
