I keep getting an address collision warning at boot time, between ACPI and Video Rom. If I add acpi=off to grub.conf the error goes away, but then I have no power management (battery icon, proper shutdown, etc.). Anyone know the cause or a possible solution?

Does anything actually not work or is it just a boot time warning and then everything works? – Caleb Jul 27 '11 at 19:40
@Caleb, just a warning and everything works so far... – rdrgrtz Jul 27 '11 at 19:52

This can probably be solved in BIOS configuration. If there is a newer BIOS for your machine, you should use it.

Other than that, try booting with pci=noacpi option. If this results in loosing some capabilities you desire, whereas presently everything works fine despite the acpi warning, you might just disable kernel warnings using loglevel=3 boot option. Note however, that this disables all kernel warnings, so if you run into problems in the future, you might need to disable this option for diagnosing those.

Thanks @jankes, I'll give that a try and report back. – rdrgrtz Jul 29 '11 at 12:58
