It's my own board, not in the mainline.

As I said, U-Boot works fine.  The problem comes when Linux boots.

I've bisected it down to this change:
   commit 81bdc155c72ef9e093b388b90c58d8134d870976
   Author: Sanjeev Premi <premi@ti.com>

     omap: gpio: Use generic API

That let me figure out the problem - I had to modify my board code
for the new GPIO functions and somehow that's where the problem is.
Still working out the details, but now I know where to look.

Thanks for the help
