I also have a similar problem on my server at home.
After testing and beating my head against the wall I stumbled across this bug report.
I have performed similar actions on Dapper, Edgy, and Feisty both x86 and AMD64 platforms.
The box usually crashes during boot. Occasionally it will let me into a
shell, or start X. But it usually dies after a few minutes.
DIsabling powernowd (chmod -x /etc/init.d/powernowd) and rebooting fixes
I will have to try leaving it enabled and using the "noapic nolapic
acpi=force" kernel options listed above.
Like I mentiond, I tested this on the ubuntu variant (not kubuntu or
edubuntu) under both AMD64 and x86 architectures under versions 6.06
(dapper) 6.10 (edgy) and 7.04 (feisty).
I attempted to test one of the versions of Gutsy, but I ran into a few
bugs that prevented me from knowing if the issue was the same.
I have attached my hardware list, kernel version, and pci list.
