Great! Thanks a lot.
It appears that even without internal ECC enabled we get failures on Micron parts, so I believe there is something else that we need to investigate. But thanks for the list, I will propose a patch preventing the use of on-die ECC together with sequential cache reads on all parts but the ones in this list (can be extended later).
Thanks, Miquèl
