Virtualbox 1.3.8 on Gentoo 2.6.20 - General protection fault

[Poulpatine]

Hi.

Virtualbox doesn't work anymore on my Gentoo 2.16.20. I've tried to delete all the settings, to create news vms, unmerge and emerge virtualbox ... but the problem is still present. So, there is my /var/log/messages about the virtualbox problem after trying to launch a vm by :

#vboxmanage startvm vm-winxp

Feel free to ask me about more informations.

I think the problem comes from KVM modules.

In fact, when I was trying to use VirtualBox, KVM driver was built-in my kernel. Now i've recompiled my kernel without the driver and I've built the driver from sources.

When kvm and kvm_intel are loaded Virtualbox doesn't want to launch a Vm but when I rmmod the modules, all is fine.

So duplicate of #374.
