Did you try to remove and reinsert the edac driver a few times, on a multi-memory controller machine?

Are 8 enough for your edac drivers too? With edac_ghes, I suspect that the worse case, on Intel side, is the Nehalem/Sandy Bridge/Ivy Bridge EX machines. Tony, What would be a reasonable maximum limit for the number of memory controllers, on a -EX machine?
