| On Archlinux we have the same problem. We have a bugreport here:
| http://bugs.archlinux.org/task/11141
| 
| Myself test it with a LiveCD/Install-ISO which has 2.6.26 as install
| kernel. We have the guest oops on virtualbox-ose, virtualbox-sun and both on
| i686 or x86_64 hosts.
| 
| Some things i noticed:
| - The system boots always when i either enable VT-x in guest settings or
|   disable acpi and run the guest with acpi=off.

 Yes, lots of ubuntu users have reported the same but another "lots"
of them have reported that the trick didn't work.

 Thanks for joining!
