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?
Fedora 15 address collision on Compaq CQ41?

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.
