System hangs after "ACPI: PCI Root Bridge [PCIO (0000:00)"

ACPI: Interpreter enabled
ACPI: (supports S0 S1 S2 S3 S4 S5)
ACPI: Using IOAPIC for interrupt routing
ACPI: PCI Root Bridge [PCIO (0000:00)

I googled for this error and I found most have this error while installing and not while booting. Did I do something wrong while configuring the system?
One solution that was suggested was use a kernel option acpi=off. I used this while installing Arch.
I will try booting with this option and let know if it worked

Thanks and Regards

if u had to use that to install then u will most certainly have to use it to boot with as well. At least that is my take on the problem.

I do believe u can turn this off (acpi) in the bios and then u won't need that boot option. But, don't quote me on that. At the same time its worth a shot.

Re: System hangs after "ACPI: PCI Root Bridge [PCIO (0000:00)"

The problem is solved. I changed my menu.lst from

kernel /boot/vmlinuz26 root=/dev/sda11 ro vga=773

to

kernel /boot/vmlinuz26 root=/dev/sda11 ro vga=773 acpi=off

It now boots and I can login as root.
Still a long way to go before I get it functional as network card, eth0,  is not detected. Will keep trying.
@jacko: I did not try disabling ACPI from BIOS as it is related to some power management. Not sure how it will effect the system. Thanks a lot for the help
Thanks and Regards

If your system supports ACPI, why did you use that option while installing Arch? Is it becasue the installation hung because of ACPI being enabled?

I do not know if my system supports ACPI. Every linux Distro I have, has been installed with acpi=off kernel option. Yes I was getting stuck at some point so I installed and now boot using that option

The following page has some information about acpi:

I have used 'pci=noacpi'.
