Hmmm. Preventing the Nvidia module from loading without disabling or uninstalling the other parts of the graphics driver can easily to a situation where the GUI is not starting. And blacklisting all modules that VirtualBox needs on the host requires quite a bit of tying at the boot loader iirc. So how about this: Quite a few kernels are also tainted because an unsuitable kernel module was loaded. This for example is the case if you use Nvidia's proprietary graphics driver, VirtualBox, or other software that installs its own kernel modules, as they might be causing the issue you face. You thus have to prevent those modules from loading for the reporting process. Most of the time the easiest way to do that is: temporarily uninstall such software including any modules they might have installed. Afterwards reboot. Ciao, Thorsten
