Odd machine behaviour

[Amichai Rotman]

I'd blame the KVM. What kind of KVM is it?

Verify the BIOS settings for the Power Management policy.

By the way, if you connect to the machine remotely, why do you even need a
KVM?

It isn't a Hibernation issue, because what you describe regarding the
machine is still on, means it is not turned off by Hibernation. What *does*
it say in the logs at the time it occurs?
