hmmm,
Ok I applied this patch and booted. I will attach the bootlogs. The
system is still not booted. I don't have the magic decoder for the NMI
reasons (I have been down this patch before with out luck).
In the boot log it says it entered kdb but there is no prompt.
Let me know what you think.

I did just see this
"BUG: wrong zone alignment, it will crash"
and am now looking into it.
