Offering this as it may help diagnose this issue. I have it operating BOTH ways on two identical systems.
System #1. Dell Inspiron 531s, Factory setup, 1 GB RAM, Processor name string: AMD Athlon(tm) 64 X2 Dual Core Processor 4000+. It reports only 1 CPU responding, (using system monitor) This system was originally built from an Ubuntu Desktop 7.10, i386. I added the Myth Frontend using the "Add/Remove" gnome-app-install I Upgraded to 8.04 using Update Manager. It apparently noticed the "myth" installation and upgraded like a mythbuntu installation. The system now starts up more like a mythbuntu system (mythbuntu logo splash), but I use it as a standard Ubuntu Desktop and only start the Myth Frontend as needed. System #2 Same hardware as System #1. It reports 2 CPUs, (using system monitor) This system was originally built from a "mythbuntu 7.10" installation and serves as a permanent mythTV backend. I upgraded to 8.04 using Update Manager. Upgrade went as expected. So I have two systems with identical hardware, running essentially the same kernel, that report different behaviors of the dual-core Athlon processor. I'm willing to try whatever you think might be helpful in diagnosing this issue. -- Athlon X2 Dual Core Processor - Second CPU/Core not working with i386 kernel https://bugs.launchpad.net/bugs/213011 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
