[CentOS] amd64_edac: probe of 0000:00:18.2 failed with error -22

amd64_edac: probe of 0000:00:18.2 failed with error -22

Logwatch shows this error on several machines - laptop and desktops -
all running C 5.6. It never appears on the data centre servers.

I have 'googled' but can not identify what error 22 is. One German
posting suggests it is related to the Error Correction Code (ECC) of
RAM.

http://en.wikipedia.org/wiki/ECC_memory suggests the problem may be
caused by laptops and desktops without a ECC facility on their
motherboards.

Can one safely continue to ignore this error?

Thank you.
