Hey,

 

I have some problems with random freezes / kernel panics on my - kind of - old hardware.

 

Hardware

CPU: Intel® Xeon® CPU L3426 @ 1.87GHz

MB: TYAN S5502 (latest Bios) 

 

I have some Docker running.

Already uninstall CoreFreq Plugin

Before I had some issues with my HBA, but after changing PCIe Slot those issues went away.

 

Is this some kind of hardware problem or could that be an software/os/kernel bug/issue?

 

It is always this "sh" process which I can't identify.

Try uninstalling the corefreq plugin.

Hmm did not notice that.

 

I uninstalled the plugin before but have not rebooted the system since.

 

I'll wait and see what happens now... Uptime 2 days, 6 hours, 40 minutes

Hello,

Apologies for that crash but this plugin is embedded an outdated version of CoreFreq.

 

See with the UNRAID CoreFreq plugin author for a refresh.

 

Vanilla CoreFreq project is developing fixes for Xeon families as soon as I am informed through GitHub issues:

https://github.com/cyring/CoreFreq/issues

 

Feel free to contact me through a fulfilled and detailed issue, titled will your processor brand string, and issue body filled with Markdown of kernel crash log, Daemon and Client outputs, like option "-s"

 

It usually don't take me lot of time to find the source of the issue and to provide a fix on the development branch for your testings.

 

Recently I have provided fixes for Server processors.

You can first try the develop branch at:

https://github.com/cyring/CoreFreq/tree/develop

 

Regards

CyrIng

 

 

21 days uptime now. I think a reboot after uninstalling the CoreFreq plugin solved the problem.

 

Thanks @CyrIng for reaching out to me, but I currently don't have time to diagnose the problem any further. Sorry.
