kernel-detected exception during startup (SELinux ? )

[ron flory]

hi-

  I saw this during first post-install startup and after
the 100+ updates.  This happens with SELinux enabled and
disabled.

  Running Acer Aspire 5601AWLMi laptop (recent system w/ 2 cores).
The same problem seemed to exist in FC6T2.

excerpt from syslog:

SELinux:  Disabled at runtime.
SELinux:  Unregistering netfilter hooks
