This is the only error I got afetr reprocessing all SPI calibrations from 18B to 24AQ01 (Feb01). Apparently an algorithm didn't converge correctly, and simply redoing the command that failed above ended with no error !

Yes there seems to be some edge cases to this that we don't understand, so this is a known error. I have a re-trial within the code that normally catches it again but I guess you hit the edge case twice!
