Random reboots

Hi everyone,

Some days ago I installed archlinux on my computer using the archinstall command. I'm not really a newbie with archlinux, I used it in the past, but I'm not so experienced either. I noticed that sometimes my system randomly reboots, even when I'm using vscode or other software for example. I'm not sure of what is the cause, but on boot I noticed a message that I tracked down using journalctl, I'll post here the output, maybe this is the cause of the crash? Can you help me?

journalctl -p err --since "today"

May 22 11:53:48 archomen kernel: mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 5: b6a0000000000108

If this is not the cause, can you please help me tracking the issue? It's not a temperature issue, I'm constantly monitoring the temperatures of my components (this was my first concern).

Have a nice day,
Giuseppe

Re: Random reboots

Post a complete journal of a rebooting boot, just filtering for errors is oftten not a good indicator for much. FWIW the only suggestion I have for this small tidbit is to ensure your microcode updates are set up. the tpm error in the second part can be normal and not cause for concern.

Do you mean the full output of journalctl -b?

Re: Random reboots

you probably want to post the full output of "journalctl -b -1", ie, the previous boot that rebooted, not the current one (that has not rebooted)

Ok, the output of journalctl -b -1 is here: https://mega.nz/file/35Ji0ZBT#FnQlpX-uN … dU_-Bep7GE
I wanted to use pastebin but it was just too big, since after the issue today there was no reboot for a few hours.

Re: Random reboots

A few of the usual realtek wifi shenanigans, nothing really pointing at a reboot. I'd still say set up your microcode updates/and or check whether there is an UEFI update for your MB vendor, a lot of ryzen CPU issues got fixed by updating UEFI

Ok, I'll follow the wiki page to install microcode. For the UEFI updates it's a little bit more complicated, my system is an HP Omen and it has an HP motherboard which requires to boot from windows to update the firmware (yes, I find it really annoying). I'll try first microcode, hoping that it will solve the issue, I have windows on the other HDD but I can't boot to it unless I unplug my NVME SSD, even if I change the boot order (another thing that in my mind doesn't really make sense).

Thank you very much for your help and your patience
