I have created and installed Fedora 9 live-cd images to my usb device.

then i begin to update some packages, well the "update" appeared to go well and while running from the usb device before during and after updates seemed good and now the "but" part upon rebooting got this message:

Bug in initramfs /init detected. Dropping to a shell. Good Luck!

the same problem experienced with Gnome and Kde. :S
