Try booting with the  acpi=off option.  However, its a bit of a blunt 
instrument. 

If you boot using Grub, highlight the Grub menu option you want,
then press 'e'. follow the instructions to add acpi=off to the end of the 
kernel line, then boot.
This is a one boot only change.  Its not a fix, just a test.

The kernel has lots of acpi knobs like this. If you have kernel 
sources, they are documented in 
/usr/src/linux/Documentation/admin-guide/kernel-parameters.txt
