This used to happen in fc1 too, but in fc1 if I moved the mouse or hit any key, the machine came back up fully (though with about a 30 sec. delay). But in fc3, if the machine ever gets in this mode, it won't ever wake up again. No matter how much I twiddle the mouse and keyboard, I never get video again. Best I can determine, I'm not getting any keyboard or mouse either (test app shows no keyboard input or mouse event messages).
The machine is techniquely still up - rlogin and vnc from on of my other machines works, and it serves http pages on my local network. If I have the network connection up, I can still shut it down with rlogin/su root/shutdown. But I don't always have another machine here. In that case, even the on/off switch won't turn the box off. Control-alt-del doesn't work anymore. Control-alt-backspace can't even be tested with no video. Typing commands at the teminal console I know is running and focussed doesn't work - the keyboard seems to be shut off too. And the mouse doesn't even light up when I move it. The only way I can shut down in this case is to yank the power cord.
I am running straight fc3 off the cd iso's, with the 'install everything' option, but a minimal + KDE install shows the same problem. (1) Tyan i845 mother board; P4-celeron 1.7 Ghz cpu; (2) 'cognac' mother board, with PIII 533 Mhz, Same behavior on both machines.
Is this a known problem? Will it be fixed by downloading a more up-to-date kernel? (I'm not in a hurry to do this, since these PC's are not near a network connection). Do I have something configured wrong? I don't see anything relavent looking in syslog.
