Ubuntu 14.10 Fast TSC Calibration Failed

This seems to be a fairly cosmetic issue, and I found a partial answer here:

For me, the timer output type was acpi_pm:

$ cat /sys/devices/system/clocksource/clocksource0/available_clocksource
acpi_pm

I edited /etc/default/grub using:

$ sudo vi /etc/default/grub

I changed:

GRUB_CMDLINE_LINUX=""

To:

GRUB_CMDLINE_LINUX="clocksource=acpi_pm" 

I then regenerated the grub.cfg using:

$ sudo grub-mkconfig -o /boot/grub/grub.cfg

After a reboot all was good.
