My Production VMwaer had Kernel Complaint: Clocksource tsc unstable (delta = 4686432946 ns) every few hours. Then it looks like the Apache Web server could not be access, to solve this problem, I did some trick to the power management ACPI OFF during Kernel Boot......

In Terminal

vi /boot/grub/grub.conf

After every kernel boot, I added "acpi=off"

Then type "wq" to write & quite the Vi

Reboot and see if it works

Editting that file will only stand until you run update-grub

The grub.conf file is generated so when a new kernel is added, the changes will be wiped as a new file will be generated without the changes.

If it works you will need to find out how to permanently add the setting but changing the file to test is completely fine
