 Hi Ben,

 When I get back from holidays I'm going to try those fixes you
recommended (using 2.4.18pre7 or later and with SUNGEM). I'm going to try
it on my Dual450 first because my Dual800 is currently in production and I
don't have another machine to replace it with at the moment. FWIW, the
Dual800 is very stable running 2.4.18pre1 (1GB) in single CPU mode, only
when I enable SMP does it lock up.

 If there is any particular thing you want me to do to test this thing
(run particular progs, etc.) let me know.

 Will do.
