We recently had a problem with extremely long IPL time. While we have solved this for now with a tidy of the IOCP, we don't know exactly what caused the problem.
It would have been a great help in diagnosing the problem if the IPL process put out messages on the IPL console to say what it was doing and how far it had got (similar to the shutdown process now does).
When I am talking about long IPL time I mean veeerrry Loonngg (i.e. 90 minutes+ in some cases.) While we have a very complex configuration with a very large number of devices this clearly indicated that some sort of MIH was cutting in somewhere - but we had no indication where. We are now back to a respectable 15 mins.
