Centos 7 minimal kernel crash on Atom platform

lpallard · Post by **lpallard** » 2015/10/06 02:13:59

Hello, in need of guidance on how to troubleshoot this. I recently built a small server using a re-purposed (second hand) Foxconn motherboard with an embedded Atom D510 CPU (taken from an old D51S mini desktop computer). This hardware has run pfsense for nearly 4 years without hardly any problem. This time I am trying to run Zabbix (monitoring software) on top of Centos 7. Having somehow limited power, I opted for a minimal no GUI install of centos 7.

All went well until I realized the server randomly becomes unreachable (SSH doesnt connect, apache is no longer available). After a hard reset, I looked in /var/log/messages only to see tons of these:

Code: Select all

I am wondering how to deal with this since I have very little experience with kernel crashes (after all why would linux crash!)

The machine consist in:

Foxconn micro ATX motherboard
4GB (2x2GB) DDR2 800
Seagate Momentus 160GB 2.5in
Atom D510 quad core CPU @1.66GHz
Supermicro CSE-512-200B chassis with 200W PSU
Centos 7 minimal updated to latest packages

If someone can shed some light on this I'd appreciate. I can and will be happy to provide any info deemed necessary to help.

Thanks!

hi lpallard,

Firstly I can't be of much help debugging the kernel crash logs you posted, I think you need an expert for that.

However I wonder if a previous version of CentOS would give you more luck, just to find out if an older kernel works better on your system. If you specifically need CentOS 7.0 for Zabbix to work you might still be able to find an old kernel version which works.

Looking at the packages on a local mirror I can see 5 kernel packages released for CentOS 7.1 dating back to March this year. One of those might give you some luck.

For instance:
http://mirrorservice.org/sites/mirror.c ... x86_64.rpm

Can you provide the output of the following commands:

Code: Select all

uname -r
rpm -qi kernel
dmesg
cat /proc/cmdline

This may not be relevant to your problem, but the Intel® Atom™ Processor D510 is a dual core processor with optional hyper-threading (2 cores with 2 or 4 threads via BIOS).

Several of these are in service here (including the system I am writing this on). I historically had terrible performance issues with the D510 when hyper-treading was enabled. None of them are currently running EL7, so I have no direct experience with your setup.

Try disabling hyper-treading in BIOS and see if the problem changes.

Funny you talk about this, but the server has been rock solid since I posted here at first (6th of Oct)....

This may or may not come back but I believe HT is not to blame since I ran pfsense for 4 years + on this hardware and never had problems with it (FreeBSD)

If that happens again I will try switching off HT!

I noticed a few things from your post:

1. You have two kernel packages installed, kernel 3.10.0.123.el7 and kernel 3.10.0.229.14.1.el7. You might want to enable the newer kernel in your GRUB config.
2. I note the following messages in dmesg:

Code: Select all

[   18.373328] IPv6: ADDRCONF(NETDEV_UP): enp2s0: link is not ready
[   18.542361] r8169 0000:02:00.0 enp2s0: link down

[   18.542451] IPv6: ADDRCONF(NETDEV_UP): enp2s0: link is not ready
[   20.709416] r8169 0000:02:00.0 enp2s0: link up

If your network connection is going up and down that could cause your problems with SSH and Apache.

3. You could try removing the options rhgb and quiet from your kernel command line in your GRUB config, this would enable you to see any error messages during boot up.

Please let us know if you get somewhere with your bug report. Or if disabling HyperThreading resolves your issue. Personally I have two Intel Atom systems and I think one might be a D510, however I've not had any problems with HyperThreading.
