You could replace the memory that is generating the errors, this error is 
indicating that your memory is having severe errors.

Or you could just rmmod the edac modules since you are ignoring the errors.

There are a number of things in  /sys/module/edac_core/parameters/ the most 
important being edac_mc_log_ce which would turn things off without rmmod'ing the 
module, but if one is ignoring the errors, the you might as well turn off the 
module.

 From the man pages it is not clear to me if syslog actually handles the 
internal kernel messages going to the console, there is also klogd, and I know 
internal messages still make it to the console even when userspace is screwed up 
badly, so I would suspect that the klogd thread in the kernel is handling it.
