I forgot to mention, 2.6.11-rc2 has new features in the selinux
(Security Enhanced Linux) infrastructure that cause problems with the
default targeted policy in FC3 - which has seen a couple of updates over
the past few days. 

I ommited part of the patch (new feature), otherwise the browsers would
not work with selinux active. Even then there are a couple of problems
that show up in my logs (portmap and nscd). If you want to use this
kernel and this causes problems you can disable selinux in the "System
Settings" "Security Level" menu (go to the "Selinux" tab). You can
disable enforcing of the policy (and you will get warnings in the logs),
or disable selinux entirely, or just turn off support for the services
that cause problems.
