Description:

When starting VMs that worked under a previous version of VirtualBox, the kernel on the host machine Oops's sometime after the guest kernel starts. This is the case for both Linux and Windows VMs.

Additional info:
* virtualbox-4.2.10-1-x86_64 with virtualbox-host-modules-4.2.10-1-x86_64
* virtualbox-4.2.10-2-x86_64 with virtualbox-host-modules-4.2.10-2-x86_64
* linux-3.8.3-2-x86_64
* Also tried virtualbox-host-dkms-4.2.10-1
* Attached kernel Oops message

Steps to reproduce:
1. Update virtualbox and virtualbox-host-modules to 4.2.10-2
2. Update linux to 3.8.3-2
3. Start VirtualBox
4. Start VirtualBox Virtual Machine
5. Shortly after guest kernel starts, the host kernel will Oops, making the host unusable.

Steps to work around:
1. Downgrade virtualbox and virtualbox-host-modules to 4.2.8-1
2. Downgrade linux to 3.7.10-1
3. Holding packages at these versions resolves the issue.

I haven't yet been able to determine if this is due to an upstream bug or if it is Arch specific.

Found a couple more Oops messages in my kernel log. I can go back further and find more that are a bit different, if needed.

I tried the following combination and get an Oops as well:
* linux-3.8.3-2
* virtualbox-4.2.8-1
* virtualbox-host-dkms-4.2.8-1

However, the following combination works:
* linux-3.7.10-1
* virtualbox-4.2.10-2
* virtualbox-host-dkms-4.2.10-2

This makes me think this is a bug in the upstream package related to a change in kernel version 3.8. Can anyone else confirm?

Regardless, I am stuck at kernel 3.7 until the bug is fixed as I depend on VirtualBox for many development tasks.

I am also affected by this issue running the lastest version available of virtualbox and the kernel. The Kernel oops is similar to the one Brandon has.
Fedora users running recent kernel seems to also be affected.

I encountered this issue today after upgrading to linux-3.8.5-1 and virtualbox-4.2.10-2. I had to downgrade back to linux-3.7.10-1 and virtualbox-4.2.8-1 in order to boot my virtual machines. Attached is the kernel Oops from /var/log/messages.log.

Here is a quick list of what I upgraded when I encountered the Oops vs what I downgraded in order to avoid the problem:
PACKAGE UPGRADE DOWNGRADE
linux 3.8.5-1 3.7.10-1
linux-headers 3.8.5-1 3.7.10-1
virtualbox 4.2.10-2 4.2.8-1
virtualbox-guest-iso 4.2.10-1 4.2.8-1
virtualbox-host-dkms 4.2.10-2 4.2.8-1
virtualbox-host-modules 4.2.10-3 4.2.8-1

I will add a similar comment to the upstream ticket as well. (Thanks for tracking that down, timemaster!)

This is still occurring with following package combination:
* linux 3.8.7-1
* virtualbox 4.2.12-1
* virtualbox-host-dkms 4.2.12-1

There exists a work-around for 32-bit guests: disable VT-x/AMD-V under Settings->System->Acceleration. I confirmed this works with linux-3.9.2-1 and virtualbox-4.2.12-3.

Unfortunately, 64-bit guests require VT-x/AMD-V be enabled so this work-around does not help.
