OK, tired with RHEL 6.5 kernel 2.6.32.431 and the two options:

Command line: ro root=UUID=034d34cd-a464-4ee3-8db9-d6061a318a16 rd_NO_LUKS
LANG=en_US.UTF-8  KEYBOARDTYPE=pc KEYTABLE=de-latin1-nodeadkeys rd_NO_MD

and saw

So it seems we had some "reclocking" taking place, but also we still have the
errors about "MMIO write" errors, and also the screen is distorted in the exact
same way like before even after just two minutes...

Any comments?

Thanks,
Andreas
