With this in mind I might start looking around the system for things which
might cause jitter in the servicing of system timer interrupts:

Are you running under a virtualized environment?
Are you running a tickless kernel? (maybe try adding nohz=off to your
kernel boot parameters)
Is there some sort of processor power saving or frequency scaling going on
that interrupts the system timer?
