cannot resume saved state with 4.1.8

I'm getting this error while resuming a virtual machine.

After doing "sudo /etc/init.d/vboxdrv setup" it works fine but at the next reboot the bug appears again. I've made sure 'carlos' is a member of vboxusers group. I've installed the extension pack. I've set the BIOS to support the hardware virtualization. I've installed and run dkms--in fact, VB demands that it be run each time I restart the computer. The virtualmachine has worked fine always in that environment and others. It happens on 4.1.8 and 4.1.9r75927.

Btw, the environment is a Ubuntu 11.10 oneiric, 64bits, kernel 3.0.0-15-server

Looks to me if your VMs don't start because the kernel modules are not loaded. Install the 'dkms' package and do '/etc/init.d/vboxdrv setup' once. Also, I don't know the script /etc/init.d/virtualbox-pilar002, it is not part of our packages. So it seems that you have some stuff modified.
