Hi, on a laptop with the new Ivy Bridge CPU I tried to install Debian testing and Ubuntu 12.04. As soon as it tries to load the setup from the boot CD the VM is shut-down. I copied the log below. Do I see it correct that the injection exception is the cause of the shut-down? What could cause the injection exception. Is the Ivy Bridge CPU not supported yet?
