Since I got a 64bit comp a couple of weeks ago I've been busy doing fresh installs of my fave distros. I decided to stick with the 32bit versions but I want to try at least on 64bit distro to see if there's any difference.
So far I've tried ubuntu edgy and fedora core 6 and both failed on boot at the same point.
I found the only way to get either of them to boot at all was to add acpi=off as a boot option.
ubuntu did install after that but I was still unable to boot once installed unless I added the acpi=off line to grub.
I haven't been able to see if fedora installs ok since there was a fault with the first disk so I need to re-download it.
Is this acpi thing going to be a factor with every 64bit distro I try?
If so what effect will this actually have on the running of my computer, will I not be able to use powersaving functions?
I don't really understand much of what acpi does since on my last computer it didn't do acpi but I know on suse I have kpowersave doing cpu scaling and both cpus are only using half their full capacity, most, if not all of the time.

Nope, acpi works just fine but you may need to build a custom kernel;


Don't let /etc/*release output fool you, I installed the redhat-release rpm from RHEL4 for update compatibility reasons I'm really running RHEL5Beta1 (updated) which is based on FC6.
