The VirtualBox-related bug is on the VirtualBox tracker as http://www.virtualbox.org/ticket/7716 . I suggest not considering that issue to be part of this one, since it has different symptoms, and seems quite deterministic unlike this one. It almost certainly doesn't have anything to do with having two swap partitions (I have that bug with only one swap partition).
