hmm... *compiler optimizations* for a specific family cause
problems on that family, but *compiler optimizations* for
a lesser family don't... I'll admit my kernel h4x0|^ 5k1!!s
aren't on par with most on this list, but has anyone thought
to take a look at the *compiler optimizations* that are
generated? It sure wouldn't be a first if the combination
of agressive optimizations and complex kernel code exposed
a subtle and/or complex bug in one, the other, or both...
and different levels of compiler might explain why some
have the problems, and others don't.

Having spent way too many hours this week looking at highly
optimized 64bit ppc assembly I can only say that <drawl
type=hick> them thar compiler hackors is devious lil
twerps when yas ask fer all the bells n wistles. </drawl>

This of course is all assuming that one or more folks do
recreate it on obviously good hardware. ;)
