After upgrading from 10.10 to 11.04 without too many dramas (I couldn't get the gnome-theme-icon package but got around that), upon the reboot it hangs after showing
Code:
install: cannot stat `webcamstudio.ko': No such file or directory
make: *** [install] Error 1

 * Modprobe webcamstudio failed. Please use 'dmesg' to find out why.
The vboxdrv modprobe also fails but it gets past that.
Everything I've found refers to problems with the 2.6.38-9 Kernel but I'm using 2.6.38-13 (other users say their problem was fixed by installing the 2.6.38-11 kernel).

Has anyone got any ideas before I go for a clean install?
