[CentOS] CentOS4 Loop at shutdown

Has anyone else encountered a loop and failure to shutdown on CentOS4?
This has occurred twice in the past month, but unfortunately I failed
to write down the looping messages. The only relevant problems I found
via Google reference raid controllers, and I have POI (plain ol' IDE).

Doh! Obviously I wuill need to record the errors.

My environment is run-level 5 with GDM, but I use IceWm instead of one
of the more common choices. IceWm shuts down cleanly. The loop occurs
after selecting Shutdown from the GDM login panel. Errata are current
as of last night.
