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

check:

#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

do:

#gedit /etc/default/grub

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=”Fedora”
GRUB_DEFAULT=saved
GRUB_CMDLINE_LINUX=”rd.md=0 rd.lvm=0 rd.dm=0 KEYTABLE=us quiet SYSFONT=latarcyrheb-sun16 rhgb rd.luks=0 LANG=en_US.UTF-8″

change to be:

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=”Fedora”
GRUB_DEFAULT=saved
GRUB_CMDLINE_LINUX=”LANG=en_US.UTF-8 rd.md=0 rd.lvm=0 rd.dm=0 SYSFONT=latarcyrheb-sun16 rd.luks=0 KEYTABLE=us rhgb quiet clocksource=acpi_pm

save .

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

#reboot

problem solved, isnt it ? :D

  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.

    Regards.
