[SOLVED] Arch on 12th Gen Intel not shutting down gracefully

Hello. Apologies for any errors in advance as I don't generally use forums.

Recently I decided to try out the new 12th Gen processors on Arch. Everything seems to run smoothly while the OS is running, but I've come accross one major difficulty. When restarting, shutting down, or hibernating, the system seems to shut down fine in journalctl, except that right after it stops, I get another screen which seems to be Arch trying to reboot.

Starting version 250-4-arch
/dev/nvme0n1p2: clean, 929682/61038592 files, 89587861/244139185 blocks
[ 1938.285023] watchdog: watchdog0: watchdog did not stop!
Unmounting all devices.
umount: /oldroot/sys: target is busy.
Detaching loop devices.
Disassembling stacked devices.

Then the terminal freezes and I have to reset the system. None of this is really a clue to where to look next, however, as the only thing mildly interesting is a famous nvidiea bug where /oldroot/sys doesn't unmount, and is likely not to be the cause of the issue.

Some errors show up in journalctl about broken PMU hardware, but that's kind of to be expected with new hardware, so I don't think that is it either. I've included the error just in case.

Using journalctl I kind of confirmed my findings, that the system shuts down fine from the OS's perspective. There is however a string of hardware errors from the last boot:

 Jan 05 12:24:37 archdesktop kernel: BERT: Error records from previous boot:
Jan 05 12:24:37 archdesktop kernel: [Hardware Error]: event severity: fatal

Jan 05 12:24:37 archdesktop kernel: [Hardware Error]:   Record Identifier: 8f87f311-c998-4d9e-a0c4-6065518c4f6d

After that is a hex dump. Searching around has only lead me to people who experienced similar issues mostly with hardware faults, but to my knowledge, the system I am running on is known good with no issues otherwise. There's no system instability during the system running, which is where other people were having issues with, mostly with their kernel hanging during boot.

Here's a pastebin of my entire journalctil -k -b -1
https://pastebin.com/fFD48y6V

The system is a Intel 12700KF with efficiency cores turned off in the bios (wanted to avoid scheduler issues, no apparent change to this issue with them on) running Arch Linux 5.15.12-arch1-1 with 64GB of DDR5. Any help would be appreciated, and I hope I provided enough information. Thanks!

Re: [SOLVED] Arch on 12th Gen Intel not shutting down gracefully

Updated my system today after a couple days away, and it seems whatever changed fixed the issue.
