fully agrees, however I had a situation once where these messages
appeared after a Kernel update. I learned that the kernel developers
added some extra error messages for my chip set with that update.
Booting an older kernel made the errors go away. OTOH, if the board is
already some years old, this is not very likely (and you will have to
replace the memory anyway.)
