Hello everyone, 
The fix common problems plugin found a hardware error on my server.
I followed the instructions and installed mcelog via NerdPack and generated a diagnostic that I attach to this post. 

I hope you can help me to see more clearly, I also noticed that one of my hard drives had an orange icon 👎 since

 

Thank you in advance

If I was going to take a guess, it's the typical AMD doesn't know how to properly design a chip and is safe to ignore

Thanks for the answer, so it would be a design flaw in my processor, I don't quite understand? 

So, I can ignore this error nothing serious really? 
 

Yes, ignore it.  Maybe I was flippant, but seems that AMD always has trouble -> whether that's with C-States, performance issues on Win 11, issuing MCE's out of the blue, etc.

Thanks for the explanations  

  

Hi,

I was about to post a topic on this.  However, this post seems to have a similar issue. I'm getting two errors.

One is a Parity failure, which I cannot find in syslog and I've changed the Parity drive a couple of days ago after preclearing twice.

 

I'm currently running a parity check at the moment.

 

The other is Machine Check Events, which I've never had before.

 

I started doing a memtest, but nothing really led me to believe it was an issue, so I abandoned it after a couple of hours testing.

Could somebody cast an eye over my syslogs to see if

I looked in the nerd pack plugin and I cannot find this module, although from what I could find it doesn't work properly anyway.

I also came across this;

Is it possible I have a memory module error?

I can see in syslog there are a few unrelated errors to do with an SMB share, which I will need to fix up. However, could somebody please give this a peruse?
