PX4 + update to 3.1.2 = no dataflash?

Just updated from 3.1-rc7 to 3.1.2 (rc2) on my Y6 + PX4/PX4IO combo. Spend about 30min in the air over 3 flights, but after the update I find that the dataflash logs are empty except for the FMT section. I’ve confirmed LOG_BITMASK,-6146 (“NearlyAll”) is / was set in the parameters for the flights, which was logging fine in 3.1-rc7 before the update.


Looks like github.com/diydrones/ardupilot/issues/817 is the culprit?
