I am using Redhat 7.2 with the current version of SELinux (2.4.17 kernel) and have noticed some "issues" (sorry to introduce Microsoftese) involving shutdown:

There are a number of access denied messages in shutdown that are hard to catch because they don't appear on the message log (since the system is shutting down).

In some cases, software (postgres and ipchains, for instance) is not properly shut down due to these denials.

I don't know whether this is related, but I get a kernel panic when shutting down in enforcing mode. It's hard to note the details of this problem because the system succeeds in shutting down anyway (so the messages disappear from the screen). I just recall the phrase 'kernel panic' appearing briefly. This is only a problem for my home computer since it shut it down after every use.

In general, I solve all of these problems by using a shutdown script that puts the system in permissive mode just before shutdown (this is not a security problem since it's hard to hack a system that is shutting down...)
