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 ?

Yes, it's working. And I can get into Linaro console now. So we need the following bits to get it work.
- Wolfram's esdhc driver (merged) - SDHCI_QUIRK_BROKEN_TIMEOUT_VAL patch - Babbage registration patch (based on Eric's bits) - Related kernel configurations
