[coreboot] H8QME-2+ boot problems on different machines.

We 64 identical machines here for now I only tried to boot coreboot on
11 of them where 4 of them got this early hang.
I switched the bootstrap processor from a machine that fails and put it
into one that always boots with coreboot, now the machine which was
failing before now boots perfectly and the other fails. Conclusion: Its
All machines here came with the B2 revision of the Opteron 8350 which
has this weird TLB failure but we also have B3 revision processors here,
so I installed a newer one and coreboot refuses to boot as well! :(
So the question is what could possibly be the difference between an
Opteron 8350 B2 and another Opteron 8350 B2?
I started to dump registers, and I'm not done yet, but so far they are

I have machines which boot with coreboot but after 4-5 tries (and when
not booting they hang at the same spot), then I have machines that boots
without any problem and directly and others which don't even after 20
and more restarts (switching machine off and on again).
Btw, thanks to your work on the h8dmr-fam10 I was able to even boot my
machines, thanks for that! :)
