I bought an Optiplex 5040, with an i5-6500TE, and 8 GB DDR3L RAM.
When I bought it, I installed Fedora Server on it. It got stuck every few days but I could never see the error. The services just stopped working, I couldn’t ssh into it, and connecting it to a monitor showed a black screen.
So, I thought let’s install Ubuntu Server, maybe Fedora isn’t compatible with all of its hardware. The same thing is happening, now, but I can see this error. Even when there’s nothing installed on it, no containers, nothing other than base packages, this happens.
I have updated the bios. I have tried setting nouveau.modeset=0 in the grub config file. I have tried disabling and enabling c-states. No luck till now.
Would really appreciate if anyone helps me with this.
UPDATE:
- I cleaned everything and reapplied the thermal paste. I did not see any change in the thermals. It never goes over 55°C even under full load.
- I reset the motherboard by removing that jumper thing.
- I ran
memtest86, which took over 2½ hours. It did not show any errors. - I ran a CPU stress test for over 15 hours, and nothing crashed.
- I also ran the Dell’s diagnostic tool, available in the boot menu of the motherboard. The whole test took over 2 hours but did not show any errors. It tested the memory, CPU, fans, storage drives, etc.
What kind of drives do you have in your RAID? Is it SMR?
The boot drive is an SSD, which is not in any RAID. I have another HDD connected via SATA. Another HDD connected via USB.
So 2 HDDs one SATA and one via USB in RAID? Can you remove the RAID drives and test it out?
Also what size are the drives and what’s their capacity?

I had problems with soft locks because somehow the PSU was in corrupt state, maybe through a black out or something. The problem persisted through reboots and power offs, only cutting power helped.
Had the same issues, it was heat.
Cool down your server, add a fan or a cooler…
I added a usb-powered fan sucking cooler air from outside the server area directly blowing it on the chassis.
That fixed for me.
It’s a long shot, but I had something similar on one of mine servers once. It was fixed by installing irqbalance and starting that daemon at startup.
This actually worked. The CPU has to get stuck, it will in a day of being turned on, or it will keep working for weeks.
Thanks a lot for this!
