Yes, I have now been able to reproduce on another board.

The System has an MMC connector, and if I boot with my SD51 SDIO card in 
the connector, then

"rfkill unblock <x>"

won't work, with x = {all,wifi,1 ...}

If I boot without the SD51 card beeing inserted, and then insert if 
after theboot has been completed,
then rfkill works as expected.

The MMC host driver is  built as a module, maybe it shouldn't.
