This is a bit better. It appears that your kernel is loading at the same
address as mine. I would like to verify this with Theseus, but that's a
job for another day just to be sure.

Anyway, according the what I have here, the trap is at _GFB+36 and the
failing instruction is:

%fff2a226 89513c mov dword ptr [ecx+3c],edx

and the values showing for ecx and cr2 are consistent, so I'm fairly
certain I am looking at the right place.

GFB probably means GetFreeBuffer and the code is failing because the free
buffer chain got corrupted. The address in ecx is clearly invalid in this
context. How it got that way we can only speculate.

I can't say much more without a trap dump.

Well, it certainly indicates a problem of some sort. This diag has a
pretty good reputation. The best way to figure out how to interpret the
results is to read the docs. If it were me, it would be obvious that I
should run the diag on a working machine to understand what the output
should look like.
