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
