The disks seem to work fine, from what I can tell.
Are the "INVALID_FIELD" messages harmless, or can they be avoided with
some tuning, or maybe with some patch?
Those messages mean that driver tried to enable certain types of
asynchronous events, but probably the hardware does not support some of
those. If you wish to experiment we could try to mask some of the bits
in nvme_ctrlr_configure_aer() function to find out which one exactly,
but for discontinued drives 4-5 years old it might not have too much
sense. It should not be critical unless you either overheat them, or
somehow else they fail and wish to report it.
