can not mount SDHC card as root partition on RaspberryPI

[MIHIRA Sanpei Yoshiro]

Hi all,

I install 10-current into RaspberryPI. But I can not mount root partition.

  - dont probe internal SDHC media as umass [NG]
  - If I set options  ROOTDEVNAME=\"ufs:/dev/da0s2a\" for external MicroSD,
    however don't mount rootfs[NG].
  - also I set kern.cam.boot_delay=15000, can't mount rootfs[NG]

  I setup below steps. Please let me to know the differences between
successor and me.

1. image file
I created SDHC Image with below URL.
`FreeBSD/Pi setup Howto'
http://kernelnomicon.org/?p=164

2. kernel 
And I built kernel with latest 10-current source tree and replace kernel.bin.

3. console output
