I cannot tell if I get a kernel panic but the caps lock button lights up. If I stop the driver service before I send the host into suspend it succeeds. The second I start it and try to suspend it fails. The failure occurs no matter what guest I've running or even without starting Virtualbox at all. Right after boot up I can try to send the host into suspend and it will fail/succeed depending on if vboxdrv is started or not. The host is Ubuntu Natty running stock kernel 2.6.38-10-generic" defect closed other VirtualBox 4.1.0 duplicate other Linux
