CPU?: Not responding

Looks like a installer kernel problem. I bet RHEL 6.3/Fedora 17 will work fine. If you want CentOS - you can try to install same system with newer/different kernel via other medium (PXE boot, USB etc), or use custom spin built with anaconda including newer/other kernel.

Google link for custom CD creation

p.s. there is no problem with Bulldozer CPU, it's supported by the kernel, I am running it.

p.p.s. you can easily specify fresh kernel initrd and image for PXE - it's easier to do

Solution 2

Assuming you've actually updated the BIOS as several people have recommended, this leaves you with two possibilities:

A faulty CPU
A faulty motherboard

Go pick up a Sempron 140 or something else cheap from a shop and drop it in. If it's the motherboard, you should continue to get these errors; while if it's the CPU the errors should stop.

In no circumstances should you try to co-locate this thing as is. You'll just have an unresolved problem that you'll have to actually go retrieve your hardware to fix.

And while we're at it, strongly consider not using a cheap desktop-class motherboard for a server that you aren't going to have physical access to. Consider at the very least a SuperMicro server motherboard with IPMI so you have some sort of remote management capability.

I'm attempting to build a system for co-location. I've been running into issues while trying to install CentOS 6.3

System Specs:

Motherboard: ASUS m5a99x Process: AMD FX-8120 (8-core Bulldozer) Memory: 2x 4gb G-Skill 2133 running at 1600

I keeps giving me an error message:
```
CPU1: Not Responding.
CPU2: Not Responding.
CPU3: Not Responding.
CPU4: Not Responding.
CPU5: Not Responding.
CPU6: Not Responding.
```
Then it instantly restarts.

I have tried installing it from USB, Multiple DVDs, Multiple Distros. I have also in the bios attempted to disable cores. I was able to disable 2/3 4/5 6/7.

I have also ensured that there is zero overclocking. The system works fine in a windows environment. I'm out of ideas.

  Have you tried a different processor? It's possible the one you have in there now is faulty. There are other possibilities, but that's what I'd do first.

  If it instantly restarted after giving you the CPU1 error message, why are there five other error messages on your screen?

  @DavidSchwartz I had attempted to put the picture above the "Then it instantly restarts". It was an oversight. I believe it goes to CPU7 then restarts quicker than I could have taken a picture or even seen it. Sorry for the misunderstanding!

  @HopelessN00b I only have one processor compatible with this board. However. As I have stated. I can install Windows Server 08/Win 7 on it with no problem reading any of the cores.

  possible troubleshooting tactic: find out what linux distros this motherboard is certified to support. install one of those and when it fails, call Asus.

  Do you have the most recent BIOS on your motherboard?

  it might be pretty simple, maybe centos 6 don't know how to deal with bulldozer cpu. For me that's the most logical explaination...

  Red Hat 6.2 supports Bulldozer, so it stands to reason that CentOS 6.3 does too. Source: news.softpedia.com/news/…

  What do you get before the first CPU not responding message?

  Perhaps your motherboard/cpu are too new for your kernel.

  Try to boot KNOPPIX Live CD knoppix.net in failsave mode to check, is this common linux problem on this particular kernel problem.

Doesn't that thread describe a totally different problem, even if it is with the same motherboard?
James over 11 years

Indeed. I can turn off all but first two cores. No success. Is it possible to disable the cores in the grub command line?
James over 11 years

I'll try disabling C1E if I can find it in the BIOS.
James over 11 years

No luck with disabling C1E. I'm attempting to find a way to boot with only core0. I can only disable in BIOS 6 of 8. First 2 remain.
James over 11 years

I misread. However, I have tried with all cores enabled and with 6 of 8 disabled. No luck either way.
brain99 over 11 years

I didn't mean that you should disable cores in the BIOS, but rather in GRUB. From the forum post I linked: maxcpus=0 or nr_cpus=1.

I will attempt this in the morning.

I'm leaning towards it being a faulty motherboard. Luckily I have somewhat access to two other exact motherboard and CPUs. I will be doing some trials with this. As for the motherboard/cpu combo. While I would prefer a SuperMicro system with IPMI. It's out of the question financially right now. I appreciate your suggestions.
