I have re-installed RedHat 7.0 on a box that was running RedHat 6.2. The problem is when you shutdown the box using init 0, before the box would software power down, now it just sits there after reporting all processess terminating, umount filesystems, every step except for the power to turn off. Thanks Rob
The behaviour has changed intentionally. The 'poweroff' command does a shutdown and power off, the halt command now just halts the machine. This matches the behaviour of other platforms.
Tried the poweroff command and still hangs with the words "Power down." and the bottom of the screen.
I fixed the problem. On Intel motherboards with Phoenix Bios, if you turn of advance power management(APM) RedHat will not be able to soft power down.
