Random Freezing and Reboots

azurepancake · 2020-08-10 12:39:03

Hello,

I'm experiencing a peculiar issue where my system will either "freeze" (locks up, any audio playing stutters in a short loop until computer is rebooted) or just suddenly reboots. Now these scenarios could be due to two completely different causes and the (seemingly) random reboots happen the most, so I will focus on that for now.

I just recently switched to Arch from CentOS 8. Note that to my knowledge, this issue did not occur on CentOS 8, and seemed to begin once I switched to Arch.

In regards to what I'm doing on the system before these reboots happen, it really does seem to be random. I may be just browsing the web or playing music.

If I review my system logs prior to the reboots, nothing stands out to me as odd. Although, I have found some kernel errors show up here and there if I peruse a bit (shown below).

I've gathered some details about my system. I apologize if it is not very helpful. If there is anything specific that would be of use, please let me know and I will be happy to gather it for you.

Again, apologies if I'm overlooking anything that would be helpful for troubleshooting this. With that, any advice would be very much appreciated.

Hardware problem is likely i think. I would search for:
[Hardware Error]: Corrected error, no action required.

V1del · 2020-08-11 10:17:13

Make sure your microcode updates are properly set up. If this indeed some issue in the CPU firmware that can often help.

azurepancake · 2020-08-12 11:49:01

Thank you for the advice. I hadn't yet applied the microcode updates, so I went ahead and did just that.

So far so good, lets see if a random reboot happens this week. If not, I'll mark this post as "solved".
