Fixed Freezing problem

I think I've fix my freezing problem in ubuntu 8.04. Just edit the file:

gksudo gedit /boot/grub/menu.lst

Then paste the three following commends at the end of the line starting with kernel:

highres=off nohz=off irqpoll

so it will look like this:

title Ubuntu 8.04, kernel 2.6.24-17-generic
root (hd0,0)
kernel /boot/vmlinuz-2.6.24-17-generic root=UUID=d85c8efa-bfd7-4d9b-8dc9-6acd26b7adba ro quiet splash highres=off nohz=off irqpoll
initrd /boot/initrd.img-2.6.24-17-generic
quiet
