Fast TSC calibration failed, Intel DX79SR
I have a box that's running SL7, intel 3930K i7 CPU, Intel DX79SR motherboard. I had to build atlas on the board, which means I had to turn off the CPU frequency scaling in the bios. In the time since (after turning freq scaling back on, and occasionally before), I've seen the "Fast TSC calibration failed" error during boot. This error locks up the machine and it doesn't make it to the login screen. Most of the google results from this error call it harmless. Does it sound like this error relates to my hardware (rather than SL7?) -- - - - - - - - - - - - - - - - - - - - - - Nathan Moore Mississippi River and 44th Parallel - - - - - - - - - - - - - - - - - - - - -

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). Are you booting up with full kernel logging enabled rather than being in quiet mode.
Re: Fast TSC calibration failed, Intel DX79SR
Thanks for the email and apologies for the delay! I had time to work on the machine and I want to make sure I understand your suggestion - things are not working yet . 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, Scientific Linux (3.10.0-229.20.1.el7.x86_64) 7.1 Nitrogen The I press " e " and am in some sort of editor. T 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 hpet, acpi_pm and jiffies and i 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 that seems successful). Is there a well-known trouble-shooting utility that I can use to diagnose bad mb, bad cpu, bad memory, etc? Any suggestions would be welcome!

Re: Fast TSC calibration failed, Intel DX79SR
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 )?
