Comment 4 for bug 117899

When you see the grub menu, select your kernel, press e, then you can
edit your kernel's boot options. append acpi=off to the line. That's all.
This line can be written into the /boot/grub/menu.lst file. This file is
auto-regenerated, when your kernel is updated by apt-get upgrade (or
utomatic upgrade). You can add persistent options that are added to the
re-generated kernel options too. See the manual and the self-describing
menu.lst file.
If you don't know your chipset you should see the other PS2/keyboard
related bug reports as well.
