Keyboard locking up in FC17

[Tod Thomas]

I've read that fc17 is end of life but maybe someone has run into this.  
I'm running fc17, latest upgrades, using XFCE, and periodically the 
keyboard just stops working, mouse is fine.  I end up having to mouse 
over ALL of my open windows saving and closing.  Once I logoff and logon 
everything works normally.  I've checked the Xorg log, messages, dmesg, 
everything I can think of but its sill happening.  I even tried turning 
off the screen saver but that didn't help either.  It happens 
inconsistently which makes it even more annoying :)

Not sure there's a single answer given the possible moving parts 
involved.  If nobody can think of anything off the top of their head 
could someone suggest a good way to try and debug?  I'll be upgrading 
here eventually but right now the timing is not optimal.


TIA - Tod
