This seems to be fixed in the latest kernel builds (i.e., Hardy, specifically 2.6.24). I'm using an Asus M5N motherboard with an AMD X2 5000+. Steps to fix for me:
1) Disable ACPI in BIOS so I can actually boot. 2) Edit /etc/apt/sources.list and add at the bottom: deb http://archive.ubuntu.com/ubuntu/ hardy main restricted 3) sudo apt-get update 4) sudo apt-get install linux-source-2.6.24-4-generic 5) Reboot, reenabling ACPI in BIOS and then selecting the new kernel to boot to 6) Comment out the sources.list line so it doesn't try to update *everything* to Hardy. (I don't know what will happen when it sees that I have a package installed that's not in any repo, though.) -- Kernel panic - not syncing: IO-APIC + timer doesn't work! https://bugs.launchpad.net/bugs/54621 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
