OK, here's a suggestion from way out in left field...  Try adding the 
kernel boot option "noapic" to see if that will help.

After performing some major surgery on my 5-year-old Myth box, including 
upgrading to 9.04, I started getting random lockups as well. Not sure 
why the kernel was defaulting to using "apic" on my Nvidia/AMD system, 
but specifying "noapic" cleared the problem for me.

E.g., here's the section I added to my /boot/grub/menu.lst file (of 
course, the uuid info is specific to my system):

    title           Ubuntu 9.04, kernel 2.6.28-13-generic with noapic
    uuid            bc3786b7-a402-4fae-89fb-3d95447bb09c
    kernel          /boot/vmlinuz-2.6.28-13-generic
    root=UUID=bc3786b7-a402-4fae-89fb-3d95447bb09c ro quiet splash noapic
    initrd          /boot/initrd.img-2.6.28-13-generic
    quiet

At least it's something simple to try  ;-)

Cheers / Ken
