Change selinux config to this (for the time being):
# cat /etc/sysconfig/selinux
...
# SELINUX=enforcing
SELINUX=disabled
...

To remove an unneeded kernel:
# yum list installed "*kernel*"
...
kernel.i686                                  3.1.1-1.fc16              @updates
...
# yum remove "*kernel*3.1.1-1.fc16*"

Now, reboot your system to your latest F16 kernel and see what happens.
