Virtualbox w Ubuntu 9.10 : vboxdrv kernel module was either not loaded

Gdy Virtualbox po skończonym upgrade Ubuntu 9.04 --> 9.10 sypie błedem

VirtualBox kernel driver not installed. The vboxdrv kernel module was either not loaded or /dev/vboxdrv was not created for some reason. Re-setup the kernel module by executing '/etc/init.d/vboxdrv setup' as root.
VBox status code: -1908 (VERR_VM_DRIVER_NOT_INSTALLED).

zamknąć i pyknąć jako root

/etc/init.d/vboxdrv setup

i podziękował :)
