This may be interesting to group members who have early revisions of 
LPC2106 still unused or in devices working in the field.
Philips have receive two sample boards which had the latchup problem 
described by me. This is the reply I received yesterday:

"The boards were experiencing a flash latchup problem associated with 
very early versions/samples of those parts (Rev. B).  The current 
revision (C) does not have this problem.  Make sure that the reset 
circuit provides at least a reset duration of a least 10ms at power 
up and 300ns thereafter.
