clocksource=acpi_pm

or

clocksource=hpet

According to the link above that line in grub may help.

see files in directory below

[root@localhost /]# cd /sys/devices/system/clocksource/clocksource0/
[root@localhost clocksource0]# dir
available_clocksource  current_clocksource

can change to =hpet even if not listed in the available_clocksource file with kernel parameter on boot up.
