OK, so I was having problems with my printer, namely, it suddenly mysteriously stopped printing. After attempting to reinstall the driver and trying different drivers , and playing with the printer, which all had no discernable effect, I decided that perhaps a recent CUPS update was the possible culprit. So, rather stupidly I uninstalled CUPS using the Gnome package manager, thinking I would reinstall it to see whether that would fix things. However, the uninstall resulted in a complete freezing the gnome window manager and subsequent reboot(s) got stuck at the last stage, namely at which the screen prints the message
Loading Fedora (3.3,2-1.f16.i686)
Loading initial ramdisk....
Any ideas on how to proceed would be welcome.
