I'm currently without any systems where I could try to reproduce it, as I moved to a new job at Samsung, and I'm still in the process of getting access to the corporate facilities and to get the needed hardware. The hardware I currently own doesn't support EDAC.
So, I doubt that I would be able to touch on that in the next couple weeks or so.
If you're urging for a fix, feel free to propose a patch. Otherwise, I'll take care of it as soon as I receive the hardware.
