	It is getting curioser and curioser: I have tried with three more 
systems, and the diagnostic keeps reappearing in two of them - with the 
same clockwork 50 minutes frequency - but not at all in the third one - 
at least it has not for a few days now. Interestingly, this last system 
is the oldest one of the lot. They are all running exactly the same Linux 
version.

	I am mystified.
