Bug Description

On Ubuntu 14.04 EC2 instances, during startup the dmesg time goes from 0 seconds to thousands of seconds. This causes kernel logs to be recorded for months in the future.

This appears to be related to the kernel trusting the TSC clock on Xen servers, as described here:

But I am not sure that is the cause.
