Kernel Panic on " AMD EPYC 7351 16-Core Processor" server

Post by bvardham » 2018/03/24 16:13:14

Hello all
we are trying to use the latest Cent OS 7.4 "CentOS-7-x86_64-DVD-1708_fromODC.iso". in the " AMD EPYC 7351 16-Core Processor" based server.

But we are facing the below error messages.

Attached in the screenshot.


could someone help me to understand that the abvoe image is supported in the AMD EPYC 7351 16-core Processor?
If not when the Cent OS official start supporting that.

Thanks in Advance.

"CentOS-7-x86_64-DVD-1708_fromODC.iso".
That is not a CentOS provided iso image filename. What is it and where did you get it from? CentOS isos are on http://mirror.centos.org/centos-7/7.4.1708/isos/
CentOS 5 died in March 2017 - migrate NOW!

We are getting same error even after using the image from above link.
I used the below image.

CentOS-7-x86_64-DVD-1708.iso

Is this an HPE-based server ? I used to have issues with HPE servers and vanilla CentOS/RHEL 7.

What is the server model ?
Do you boot in UEFI or BIOS mode?

Did you solve your kernel panic ?

I am running Centos 7.4 on a dual-Epyc Supermicro box, the following is the inxi output:

And it "seems" to run fine, however , at random, when the machine is nicely loaded with a couple of KVM/QEMU guests on an SSD, postgresql on an NVME, also lots of http-php requests doing image convertion using convert, and also serving NFS on a partition............

it reboots. nothing in the /var/log/messages about it either.
example, this is a snippet from the messages during one of those random reboots:

And I haven't the slightest clue as to why. The server is certified by Supermicro to run Centos 7.4, and the performance is usually great, lovely box, if it wasn't for the darn reboots....
