I have the same problem on Feisty AND Gutsy. It is definitely kernel problem - if I run 2.6.17-11 (or older) everything is ok, but on 2.6.20.* power down does not work, as mentioned above.
It is somewhat annoying, and I can switch between kernels on the same system - so maybe I can help you somehow? btw, restarting works ok -- Shut Down won't power off https://bugs.launchpad.net/bugs/42160 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
