The failure can manifest itself in many ways, I have only seen it as a read failure, but there should be no reason why it cannot also show as a write failure.
It should be in the later vanilla kernels, it won't be in the earlier ones, I would do a find /lib/modules -name "*edac*" -ls
It is a hw issue, either something is running faster that it should be (pci bus set to fast for the given hardware/config) or something is broken.
