I found a system with a 5000X Memory controller (which should have the
same errata). It doesn't have the faulty bit (perhaps better BIOS). I
was able to findout why the code in the previous patch wasn't working,
but wasn't able to cause the crash by setting the bit from the errata.
The reworked version of the previous patch found below should resolve
the issue. Please test it if you can.
Will be happy to test, but patch appears to be against a different tree?
