Hi, I have a similar problem, when i try to boot form live CD the boot stops at "ACPI: power button [PWRF]", i resolve that with: noacpi=off and idle=poll.
Then I installed the system. But now I have another problem when I try to boot, I have the same error again, I tried to set the grub.cfg same settings (noacpi=off, idle=poll), but still says ACPI: power button [PWRF]. Any idea?
Tnx
