Solving error: [ 0.000000] Fast TSC calibration failed when booting in fedora 16

Getting error while booting in fedora 16 like

error: [ 0.000000] Fast TSC calibration failed when booting in fedora 16


#cat /var/log/message | grep TSC

this is to show log message of TSC

#cat /proc/cpuinfo | grep tsc

#cat /sys/device/system/clocksource/clocksource0/available_clocksource

#cat /sys/device/system/clocksource/clocksource0/current_clocksource

this problem are : counter time stamp > synchronization time maybe in network app when booting is to slow/fast


#gedit /etc/default/grub

GRUB_CMDLINE_LINUX=” rd.lvm=0 KEYTABLE=us quiet SYSFONT=latarcyrheb-sun16 rhgb rd.luks=0 LANG=en_US.UTF-8″

change to be:

GRUB_CMDLINE_LINUX=”LANG=en_US.UTF-8 rd.lvm=0 SYSFONT=latarcyrheb-sun16 rd.luks=0 KEYTABLE=us rhgb quiet clocksource=acpi_pm

save .

#grub2-mkconfig -o /boot/grub2/grub.cfg


problem solved, isnt it ? 😀

  1. I’ve been trying to fix this recently on Fuduntu 2013.2 but nothing seems to work. I have no problems on my laptop but it’s my only OS. Putting it onto my main PC and that error happens. Any chance you, kind sir could help out a nooblet


  2. Hi, I don’t think this is actually the best way to deal with it, it’s like what the ostrich does, you know, like hiding our head in a hole hoping for the problem to go away…

    No, what the clocksource=acpi_pm is just set it to acpi_pm, somewhat a ‘failsafe’ method but definitely not the best.

    In modern distributions I suggest you to try clocksource=tsc as it is an improved way to handle this clock.



  3. i keep getting the tsc calibration failed error on kali linux i am on am hp everytime i boot it takes me to the grub loader and i load debian gnu and it gives me the error and the screen goes black , please help me


  4. I’m new to Linux. I flashed a .iso image of Lubuntu to a flash drive to function as the OS for my final project (mineral oil submerged PC). I get the exact same error on boot up. I see that someone has provided a fix, but what I need help on is how to implement the fix. Where do I enter the “script” that OP provided? I am new to Linux, pardon my ignorance.


  5. But how do you guys modify grub if my system does not boot ? It hangs with the tsc calibration error message….It is not even reachable via ssh from another machine 😦
