Your mother boards are probably not 100% the same, maybe a chipset is
newer and causing an interrupt problem.  I've seen this before.  Put
'acpi=off' in your kernel boot parameter line in the grub menu.lst
like this:

title           Debian GNU/Linux, kernel 2.6.18-686
root            (hd0,0)
kernel          /boot/vmlinuz-2.6.18--686 root=/dev/sda1 ro acpi=off
initrd          /boot/initrd.img-2.6.18-686
savedefault

Reboot, and that should do it.
