No SD card in the system. At least not on my mx23evk board.
My real target hardware has a SDIO wifi chip.

Are you also testing on the mx23evk board? Really strange it is not
reproducible here then.
Anyone using mx23evk please give:
- revision number of board (I have tested on rev C1)
- kernel parameter used (see previous mail for mine)
