Pressing the power button for many years has worked fine for 
both Windows and Fedora to start a shutdown on these systems. 
It is only recently that pressing the button while at the fedora 
logon screen, it goes it to what appears to be some kind of 
hibernation mode with the power light blinking. Touching the 
keyboard seems to make it seem to do something, but it never 
wakes up, and at that point Ctrl-Alt-Del, and any other 
combination of keys do nothing. Only pressing and holding the 
power button will shut it down or turning off the power on the 
power supply. Then the next restart requires another restart. 
Windows XP will do a regular shutdown when pressing the power 
button. 

These machines are from 2005 with AMD FX 55 64bit CPUs. 

Have found some kernel options that I will try to see if they affect 
the process.
