the patch does fix the sudden halts that I was seeing with
2.5.42-mm2. The system has now survived about 10 successive kernel
compiles and it is still running.
There are a couple of odd things going on, though - but I don't know
for sure if they are related to the mm patch or not. I am seeing these
messages regularly - disk activity seems to provoke them.
