I had the same problem. Ubuntu 7.04 crashed very frequently – several times per hour(!). If you see the error message 'MP-BIOS Bug 8254 times not connected to IO-APIC' at boot up you probably need to activate the noapic option in /boot/grub/menu.lst as described in http://ubuntuforums.org/showthread.php?t=430674&highlight=8254 . In my case at least it resolved the problem. By the way: My Laptop is equiped with a ATI graphics card (ATI Mobility Radeon 9600 M10).
