Permanent Failure
When the system detects that the service processor is permanently, completely
failing, the system receives a service processor damage machine check. The
system also notifies subsystems about the damage.
For a permanent failure, the system issues the following message:
ISN000E THE PROCESSOR CONTROLLER HAS FAILED. SOME CRITICAL SYSTEM
FUNCTIONS HAVE BEEN DISABLED. AN ORDERLY SHUTDOWN OF THE
ENTIRE SYSTEM SHOULD IMMEDIATELY BE ATTEMPTED IN ORDER TO
MINIMIZE THE IMPACT OF THIS FAILURE
After this message, the operator can optionally perform an orderly shutdown of
the system. Processing can continue, but when a function of the service
processor is required, the system may become inoperative. To recover, the
operator then performs an initial microprogram load (IML).
Peter, did you try the IML? I am not even sure what that means anymore on
today's equipment.

OK, here's the story so far:
We've tried IPLing a few times, and later performed a power-on-reset, but
still got the message a few hours later.
Unfortunately, they do not have official IBM support (assuming they would even
support such old machines), and I don't think that's about to change, given the
ongoing migration to open systems.
I still can't find anything interesting in the logs and I am running out of
ideas.
The only thing we could think about that might be related is a power failure
we suffered a day before the message appeared for the first time.
