today i did a little testing on my G4 regarding this issue.
the point is that an _unoptimized_ kernel (i.e., building the kernel
w/o any settings in /etc/mk.conf) crashes while booting the machine
(please follow that URL above for details), while
i) a kernel built with mcpu=7400 and/or mtune=7400,
ii) a kernel built with -maltivec and/or -mabi=altivec, and
iii) a kernel built with -O3
as well as _any combination_ of the above mentioned optimizations lead
to a _running_ (and rock solid) machine.
last tested with 3.99.3 from today.
if i can do anything to help fixing this, please mail me.
