Server crashing, segfaults, null pointer dereference, unable to handle page fault...

[apool]

Hi everyone, I'm in dire need of help. For the past few days I've been trying to setup a server using second hand components, but I can't seem to even complete a first boot without the server crashing on me.

 

First of all, my components are an i5-10505, 8gb Hynix RAM (HMA81GU6AFR8N-UH), asrock b460m-itx/ac, nothing else is plugged in besides the cpu cooler, monitor via HDMI, keyboard. My boot drive is one of the recommended in the docs, a Samsung bar plus 64gb, plugged into a 3.2 port, as my motherboard doesn't have a 2.0 one, just a header connector for them. Running version 6.12.9, just because I thought maybe it was something in the latest version that was causing issues, but no.

 

I don't know how many times I've flashed the boot drive (and manually inserted the key file as unraid recover services wouldn't work). The first boot would go okay, I could set up a root password and log in to the dashboard, but out of the blue the webUI would become unresponsive and eventually time out to a 500/504 internal error, and on the plugged monitor would appear a lot of lines regarding errors (see attached photos). Ran memtest for 6 hours before I had to stop it, 5 passes, no errors.

 

The errors I have encountered are: Bzimage checksum error, bzfirmware checksum error, BUG: kernel NULL pointer dereference, BUG: unable to handle page fault for address, some segfaults at first...

 

I'm not skilled enough in this area so please bear with me. I've tried with a spare motherboard I had, a MSI H150M PRO, and the same would occur. Do I have a bad CPU or RAM?

 

Attached you'll find the diagnostics compressed file, also a file named 'syslog-previous'. Please let me know if you need anything else.

 

Also I can't seem to shutdown the server, I'll try 'sudo shutdown now' and wait the graceful period and it won't do nothing, I'd have to force a shutdown turning off the PSU.

 

Please help me, I've tried to remember everything and go into detail, thank you all.

Start by running memtest.

Done that already, ran for 6 hours, no errors, had to stop it. I'll update #1

If you have a different DIMM try with that one, memtest is only definitive if it finds errors.

I do not have a spare stick, I could get one from my PC though. Will try in a few hours

Tried a different RAM stick, no changes. I do have a spare mobo and CPU, I'll try with that and report back. EDIT: CPU is 11th gen and my mobos only support 10th gen, I'm out of options.

 

No one can help me here?

So yeah, I have gotten ahold of another cpu + mobo that could support it and Unraid is running fine as of now, so I think I may have a bad CPU
