I fixed this by loading the second most recent kernel
(2.6.11.1.1369_FC4) instead of the most recent kernel
(2.6.14-1.1656_FC4) from the Grub menu.  A lucky guess -- does anyone
have any idea as to why this worked?  For example, what does the
difference between "1369_FC4" and "1656_FC4" mean in the name of a
kernel?
