My machine is an old Compaq Deskpro with a Pentium II 333MHz (ouch!). I have this same problem running Ubuntu 6.06.1, and also with Debian Etch. I loaded up a Knoppix 5.01 CD, and it has the same problem. Now it gets strange. I had FreeBSD 6.1 loaded on the machine, and it had the same problem, it wouldn't power off after a shutdown (none of these will do a shutdown/restart either). I also have Solaris 11 b46 on this machine (I'm a masochist) and it powers down and restarts just fine.
I've tried all the apm/acpi settings mentioned above, and none had any effect. I'm going to try downgrading to Ubuntu 6.06 (or even 5.10) and verify that it worked then. I tried loading Edgy knot-3, but it hangs at 59% through the installation (3 times consistently). Debian Etch and FreeBSD 6.1 work fine on my Dell Optiplex and a white box P4 machine. -- Power down after shutdown does not work... https://launchpad.net/bugs/43961 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
