Though google search shows many results with same error, no links guided me to resolve this issue for me ..
I am trying to run rowboat-kernel-2.6.37 on my beagleboard xm Rev.C. but I am facing an issue while the kernel is trying to mount the sd card partition(/dev/mmcblk0p2) containing the root file system.
part of the boot log showing this error is as below,
Waiting 1sec before mounting root device...
mmc0: host does not support reading read-only switch. assuming write-enable.
mmc0: new high speed SD card at address e624
mmcblk0: mmc0:e624 SU02G 1.84 GiB
mmcblk0: p1 p2
VFS: Cannot open root device "mmcblk0p2" or unknown-block(179,2)
Please append a correct "root=" boot option; here are the available partitions:

I am sure that the issue is with rowboat-kernel-2.6.37 kernel, as replacement of the rowboat-kernel-2.6.37 by an angstrom kernel worked fine.
I guess there should be a kernel patch for this issue.
Hoping for help from all the geeks here..
