You have a Compaq R4000 notebook with AMD 64 4000+ (2.4ghz) and Ati Radeon Express 200M graphics.
You need to do this:
Reboot your system and hit the escape key when grub says its going to boot your default kernel in a few seconds. This takes you to the grub boot menu. Select the kernel you would normally boot with the arrow keys and hit "e" for edit. Add the string, " no_timer_check=0" (without the quotes) to the end of the line and then hit enter. The parameters are blank delimited so leave a blank between the string you add and the rest of the line. This takes you back to the grub boot menu and then hit "b" to boot using the same kernel but now with the modified boot parameters.
If you're happy with the result, edit the file /boot/grub/grub.conf to add the, "no_timer_check=0" option. Updates appear to bring this forward so you don't have to worry if you install a new kernel.
