I am not following closely the BeagleBone kernels, but from the boot
log it seems like the MMC card is not detected. Several possibilities:

 * The MMC support is not enabled in the kernel configuration, or the
   proper MMC driver.

 * The MMC device is not described in the Device Tree and/or the
   support for MMC on this platform is not available.

The version of the kernel being displayed is just 3.8.11, which
indicates a mainline kernel (which doesn't support MMC on AM335x, as
far as I know). However, our beaglebone_defconfig uses a TI custom
kernel, which I believe, should show probably show a different kernel
version than just 3.8.11.

Can you send us your Buildroot .config file?

Best regards,

Thomas
