SD card probe failure

I'm loading barebox as a second stage bootloader, because I haven't figured
out yet how to boot it from SD card directly. It seems though as if barebox
in general is not happy with the SD card:

barebox 2012.05.0-00194-g38d361d-dirty #0 Mon May 14 10:52:47 CEST 2012

sid1-noah:/ devinfo mci0

 No information available:
  MCI card not probed yet

sid1-noah:/ mci0.probe=1
imx-esdhc at imx-esdhc0: timeout 1
Cannot reset the SD/MMC card
set parameter: Connection timed out

Any ideas? What are possible causes of this?
