Right, taking notes from the dupe bugs 524477, 525218 and 525616.

The problem is that some motherboards (like many Gigabyte mobos) do not have a correct way to switch on/off the ECC memory or does not have a switch at all.

Now, the kernel sees that ECC is disabled and gives a warning.
Actually kernel 2.6.32-13 did only that, but the newer one, 2.6.32-14, gives also an oops, which is a bug (=too high level action).

You can, as a workaround, blacklist the module x38_edac.

To do this, create a new file named edac.conf and put only this line in it:
blacklist x38_edac

The file should be then put into this folder:
/etc/modprobe.d/

This will prevent the module from getting loaded.
And of cource then the error detecting feature is off regarding ECC memory, meaning no ECC.
But then again, no probel if the motherboard does not support it anyway.

  * Avoid another way that edac complains loudly. (LP: #525792)
