System crashes and reboots every 15min - 2hr

[Justin Moore]

I have a NUC11NAHi5 system running Ubuntu 20.04.3, and every few minutes to hours it will crash:

When it comes back up I see the following errors in journalctl:

followed by a large hex dump. It could be related to this issue:

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).

System: NUC11PAHi5

BIOS: PATGL357.0041.2021.0811.1505
Board: NUC11PABi5
CPU: i5-1135G7

I'm not sure if it's a kernel issue, BIOS issue, microcode issue, or hardware issue, so I decided to start here. Let me know how else I can help.

Updates:

- The hardware passes multiple rounds of memtest86+ over a ~10 hour window and does not reboot during that time

- When left at the BIOS screen for hours on end, it does not reboot

- The system will do the reboot cycle under all kernels I currently have installed, which includes:
5.14.0-1020-oem
5.14.0-1018-oem
5.13.0-27-generic
5.11.0-40-generic
5.11.0-38-generic

By process of elimination this is starting to look more and more like a Linux kernel issue.

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

[Justin Moore (justinnonwork)]

It had been fine for a little while after I replaced the hardware, but starting maybe a month ago I started seeing it again. Adding to the list of problem kernels are:

5.14.0-1044-oem
5.15.0-50-generi

Status changed to 'Confirmed' because the bug affects multiple users.
