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 the issue. 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. ** Attachment added: "Hardware List" http://launchpadlibrarian.net/8918685/cabal_hw -- System freezes whilst powernowd stepping up AMD64 freq (intermittent/hoary) https://bugs.launchpad.net/bugs/16961 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
