Description of problem:
I have had a kernel panic that I think it's related to using two KVM virtual machines.

Version-Release number of selected component (if applicable):

How reproducible:
I have reproduced it a couple of times. It has happened when I was playing with two VMs (Whonix: http://sourceforge.net/p/whonix/wiki/Home/#whonix-homepage - they are i686 Debian images).
Some months ago, I used another KVM vms in F18 without problems. In these months I have updated the UEFI BIOS firmware and touched some parameters like setting "max performance" in the BIOS and reserving 1024M to the SandyBridge GPU.
My motherboard is an Asus P8Z68-V LE with BIOS version 4002 and a Intel Core i7-2600K

Steps to Reproduce:
1. I start two VMs
2. Play a little with them
3. Crash

Additional info:
I have configured kdump and this is what I see. If you need the vmcore file I keep it, it's 9,3GB

# crash vmcore /usr/lib/debug/lib/modules/`uname -r`/vmlinux

This kernel works perfect for me. I've been using it for two days and I haven't got any more crashes. I've been doing extensive testing with 5 vms without problems so far. Before, with kernel-3.9.9-301.fc19.x86_64 I had 3-4 crashes per day.

Thank you!

Great, thanks.  I'm going to mark this as a duplicate then.
