I can report that setting "acpi=force" does not solve the shutdown/reboot problem for me, running Lucid on an aging (but still good!) amd64. The last LTS, 8.04, was able to correctly handle this same hardware.
During the shutdown process, I can hit ESC to see the messages go by. The very last line says "Killed," and there it stops, power supply still running. The only way to reboot it is to hit the reset switch or power button. uname -a: Linux mwamizi 2.6.32-27-generic #49-Ubuntu SMP Thu Dec 2 00:51:09 UTC 2010 x86_64 GNU/Linux ** Attachment added: "output from lspci" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/576204/+attachment/1792284/+files/lspci.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/576204 Title: lucid doesn't shut down completely -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
