This is great! Thanks for the help.

Minimized clock and maximized vga settings slowed it enough to get an 
idea of where the kernel is throwing a fault.

The kernel boots for quite a while then just after some "cgroup" stuff 
it mentions a line about L1 cache, a few more lines, then something 
about "Performance events AMD PMU driver"

this is followed by a --cut here-- and the next line says something 
about enlighten.c

This isn't a lot to go on but I hope it points to somewhere recognizable.

I can try to localize it more with some help.

Thanks again,
Mike Wright
