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
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.
