Ok, thanks. I was based upon Tony's -rc5. However, I rebased to the same
as you and it is still working for me
Can you send me your .config?
At the same time, maybe just try "make omap2plus_defconfig" and enable
the OMAP3 debug devices config. That's all I am doing.

Ok, should be fine. The kernel should print the ES version on start-up ...
[ 0.000000] OMAP4430 ES2.2
What does yours show?
