TSC calibration error (Linux, DX79SR + 3930K i7 )

I have an linux box (Red Hat 7) that doesn't quite work. On boot, I get a error stating that "Fast TSC calibration failed." According to google this seems like a common and harmless error, but it locks up my machine and the bootup doesn't complete.

Is there a way to test my hardware (CPU, motherboard, ram) to see if my hardware is faulty? I've just upgraded the bios in the DX79SR to be the most recent version available, and it seems functional.

The DX79SR has lots of overcloacking features that I'm not interested in using. Could an errant BIOS switch choice be the sort of this problem?

Any suggestions appreciated,

Nathan

Hello, apricot:

I would recommend to post this on https://access.redhat.com/discussions?keyword=&name=&product=All&category=All&tags=All Discussions - Red Hat Customer Portal.

Thanks. I think the problem ended up being with the specific linux kernel I was using. When I included the line clocksource=tcs in the kernel boot line (within grub), the problem went away.

 

Also, when the machine booted up, I ran yum update and rebooted (without catching the grub menu) and the TSC error, again, went away, so maybe it is a problem with just that kernel, Scientific Linux (3.10.0-229.20.1.el7.x86_64) 7.1 Nitrogen.
