Not sure about what are you complaining, since you didn't show how was
the log before.

>From the above, what looks weird, from EDAC driver PoV, is:
	[   12.506298] EDAC sbridge: ECC is disabled. Aborting

Does it used to work before? If so, was there any BIOS setting change?
Does the memories used on this machine have ECC?

Mauro
