Bug Description

I have Ubuntu 14.04 and Windows XP running in a Virtualbox VM.

If I suspend the Ubuntu 12.04 host once, all guests in Virtualbox become too slow to be usable. Meaning a boot takes almost half an hour when it would previously take only 30 seconds. My host machine is an I5-4570 4-core with 8G of RAM.

This is a fairly new phenomenon, I did not notice this before a week ago (or so). Some update must have broken Virtualbox or the kernel.
