We have several Dell Precision WorkStations, and I see this problem on
exactly 1 machine so far (Dell Precision 450, dual hyperthreading
Xeons). (User logs in using either GNOME oder KDE - machine freezes, power
off/on cycle necessary). Because these are production machines I did not
try to disable SMP but reinstalled the previous xorg-x11 RPMs and the
problem went away. Our other machines with identical hardware don't seem
to be affected - strange.
