I upgraded my system earlier this evening which went through without any warnings. Upon restart, my system started to "stall" / "freeze" every minute or two for about 5-10 seconds. It basically became unusable as everything would just halt. Mouse and keyboard included.
I quickly restored a backup and everything was fine again. I decided to update again (this time from terminal) and start troubleshooting what did break on my system.
After some quick checks (and the random "stalls" returning), the only difference before and after the update I could find was (using sudo journalctl -p err --since today)
nov 16 23:59:10 XXX kernel: iTCO_wdt iTCO_wdt: can't request region for resource [mem 0x00c5fffc-0x00c5ffff] nov 16 23:59:16 XXX lightdm: gkr-pam: unable to locate daemon control file
I then rebooted and reverted to the 4.19 kernel I have installed for emergencies like these and behold, no more freezes or halts.
The last good Kernel I had working here was 5.3.8 I believe (which isn't available in Manjaro kernel manager anymore). So I'm pretty sure it's something between the kernel and my system.
Here my inxi:

I would appreciate any help to try to solve this.
