Re: Fast TSC calibration failed, Intel DX79SR

[Nathan Moore]

Resolved.

Thanks for the suggestion.  When I included the line clocksource=tcs, 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
​​)?

Try removing these two lines so that if the error is something else it
will be printed

I had time to work on the machine and I want to make sure I understand your
suggestion

.

When the machine boots, I get a grub screen that allows
​m​
e to choose between 4 kernels (2 versions, and their debug version twins).

I select this one,

hen append "clocksource=acpi_pm" to the linux16 line, so it reads something
like:

​linux16 /vmlinuz-3.10.0-229.20.1.el7.x86_64 root=UUID=b7.etc ro rhgh
quit Lang=en... systemd.debug *clocksource=acpi_pm*​

​then Ctrl-x to boot?​

​I've done this with

n every case, the tsc error appears and the machine refuses to boot. The
machine also refuses to run the installation CD
​ (I assume ​b/c its trying to so the same kernel boot?).

​Does this sound like a hardware error?  The (intel) bios is updated (and

​Any suggestions would be welcome!

Most of the google results from this error call it harmless.  Does it 
sound like this error relates to my hardware (rather than SL7?)


My Dell Precision M6500 throws the Fast TSC Calibration error every 
three or four boots; it doesn't lock it up (in fact, it threw the error 
when I booted it today, and it's still running several hours later).
