But when I try to login console, it gives a bunch of error messages like below.
mmcblk0: error -110 transferring data, sector 1737392, nr 2, card status 0xe00

As you have tested Wolfram's bits on i.MX51 (eukrea?), probably my
babbage registration bit is causing problem. Could you please help
have a review to see if anything incorrect?
I just tested a linaro rootfs on SDCard (we have a nand flash so until now we
had our rootfs on it) and got the same errors as you.
As suggested by Richard, SDHCI_QUIRK_BROKEN_TIMEOUT_VAL seems to fix the
problem, so can you try the following patch ?
BTW, concerning Linaro's rootfs, I didn't managed to get a login prompt on the
serial port because of udev problems certainly because I'm missing options in
the kernel configuration, but at least I don't have anymore mmc error messages.
