The RH3.0 is a patch version already (2.4.21-20.EL). But no, there's no chance
of trying anything else.

I had installed and enabled (apparently temporarily) some error logging thing
I had been pointed last week, it seemed to have caused some extra info to
appear in /var/log/platform:

I had run some more tests this week which also caused crashes, but this
is the entire file.

                                Thanks,
