Working under OSX doesn't indicate good memory. I had severe problems
on my iBook G4 under linux and none under OSX. Apples hardware test
cd luckily revealed bad ram. According to benh this has to do with
the way linus and OSX use memory (see the list archive).
Anyway, this case seems to be different and turning CONFIG_PREEMPT 
could do it.
