My C2D Q6600 quits with a trap 16 or 18 (I have all withness and debug
support deactivated at the moment).
The Intel i3-3220 crashes with blinking characters on the screen (I use
the built-in GPU for console displaying).
A C2D 8400 - same setup, crashes also very early while booting.
The whole system/world is built with CLANG, this is the setting of the
/etc/src.conf:
CPUTYPE?=3D native
#
CFLAGS+=3D -O3 -pipe -march=3Dnative
# for Kernel
COPTFLAGS+=3D -O3 -pipe -march=3Dnative

I have a custom kernel, will try also the GENERIC and report in later.
