TOSHIBA ACPI problem

Hello, how are you?
I’m trying to install FreePBX in a Toshiba L645.
When i try to boot the CD i see the following
ACPI: Processor [CPU0] (Support 8 throttling states), and freeze here.

This sound like ACPI problem, but i can’t do nothing into toshiba bios.

ideas?

Thank in advance
Regards
Cristian
