Hello, I have been running Ubuntu Linux with little or no problems for the past week on a new system. It all started when I enabled hibernation and upon powering the system up this morning I noticed an error message stating that ACPI was disabled. My other system seemed to have trouble hibernating in Ubuntu as well, but it always recovered from the errors after a few reboots.

I also have Windows XP in a dual boot and it doesn't make it past a blue screen message about ACPI being disabled. So I'm wondering if my bios was corrupted somehow, or if there is hardware failure. My motherboard is an AsRock ALiveNF7G-FullHD R3.0. Thanks for any help.

Well, i do know windows won't boot with acpi enabled unless you did the f6 raid setup at install, other than that, i dunno, GL.

The problem was fixed by doing a CMOS reset.
