Description of problem: If you're shutting down the system locally (Click on Shutdown under KDE or Gnome) the system is shutting down and power off. If you're shutting it down via ssh remote-console, the system is going down, show's system halted, but nothing happens. 5 seconds on the Hardware- PowerButton helps. Version-Release number of selected component (if applicable): 2.6.22.9-91
Did you use "shutdown" or "shutdown -h". If you don't use the -h option, shutdown doesn't even try to poweroff/halt the machine.
this was the failure. shutdown -h -t secs: 00 works fine. sry for the mistake and close this thread, please greetz µatthias
