The SD_STATUS and SEND_NUM_WR_BLOCKS commands are supposed to cause the card to send data back to the host. However sd.c was missing the state change to sd_sendingdata_state for these commands, with the effect that the Linux driver would either hang indefinitely waiting for nonexistent data (pl181) or read zeroes and provoke a qemu warning message (omap).
