Waiting for root device /dev/mmcblk0p2... mmc0: error -110 whilst initialising SD card

```
What steps will reproduce the problem?
1.I used procedure mentioned in rowboat site for beagleboard C3. Downloaded
2.6.37 kernel gingerbread as per the details mentioned in site

2.copied root and system folders to android_rootfs and created rootfs.bz2
3.

What is the expected output? What do you see instead?
It should mount rootfs and give login prompt but the error is

Waiting for root device /dev/mmcblk0p2...
mmc0: error -110 whilst initialising SD card

What version of the product are you using? On what operating system?
I downloaded 2.6.37 kernel gingerbread

Start with the attached beagle_error_log.txt and the reported boot log for the 2.6.37 Gingerbread kernel on the BeagleBoard C3, focusing on the /dev/mmcblk0p2 wait and mmc0 initialization error. Reproduce the boot procedure described in the issue; done means the rootfs mounts and the system reaches a login prompt.
