Reboot of Ubuntu on Alix boxes

I own a Alix1.c (GeodeLX) Box. I installed Ubuntu 8.04 to a harddisk that is connected to this box. Always when rebooting i discovered that something fails and the system hangs switching the display on and off all the time. I got the tip to try to switch off the kernel splash screen which might be the reason for this behavior. What should i say… thats the solution.
Just remove the “splash” in the line with the kernel arguments in /boot/grub/menu.lst and save the file.
After next reboot the shutdown and reboot will work.
