Booting issue on pandaboard 4460 Rev B2

Hi,

I have pandaboard Rev B2 with me. I am trying to run ubuntu 11.10 on the same and followed steps which are given on http://www.omappedia.com/wiki/OMAP_Ubuntu_Core.

My board hangs in booting. Below is the log of the same.

I also tried ubuntu 12.10 from the same link but the kernel stops booting at below mentioned state.
