Yes - there have been multiple attempts to re-calibrate nnaida7 ADCs

Note *all* ADCs were calibrated before the most recent FEE64 power cycle.

It is not unusual for ~1-3 FEE64s to fail ADC calibration tests following
a power cycle - there is no obvious pattern to which ADCs fail or which (if
any) will be successfully re-calibrated.
