[CentOS] System hang during shutdown (halt)

Alle,

	I'm running V5.3 (newly installed) on an FJ E8020 laptop. The problem I 
have is when shutting down (*not* rebooting). NetworkManager fails to 
stop and after (during?) the postfix shutdown, the system seems to hang. 
I cannot access via another screen or remotely. I can't find any clues 
in the log files. I could use some suggestions on troubleshooting.

Here are the active services:
