Crash after calling corefreq-cli

[ich777]

Hi, got a report about a crash after issuing the command corefreq-cli. The system is a Intel Xeon E5-2630L running on a Supermicro - X9DRL-3F/iF maybe you can tell what caused this. I link the forum entry with more information here too: Click

Let me know if you need more information!

Oh, I found this in the syslog after it installs the CoreFreq plugin on unRAID:

If the PMU version is greater than 3 then the Uncore is programmable

For testings a fix is available in branch develop of CoreFreq v1.87.3

[cyring]

Please show me if fix is solving the crash ?

Observe that SNB/EP Xeon(s) are therefore losing the Uncore counter.

[ich777]

The user doesn't responded yet on the forums, will keep you updated...

[cyring]

OK, fix is waiting in development branch
