Hi Rich, AH! :) Thanks for the informations! >From what you say, it is a kernel problem, since the kernel is the one who switches off the lights... But even if I use the same kernel as used for the Debian system it does not work... May be shutdown says "power off the system" and the kernel understands "reboot the system"? I mean: In principle the kernel would be able to poweroff the system but there are some communications difficulties with the guys from userland? ;) Best regards, Meino
