Do you have the ID pin grounded or how do you get to the
A_IDLE state? I'm pretty much only testing with loadable
modules as in omap2plus_defconfig, I don't think I've seen
this issue..

Maybe check the changes in your .config against just plain
omap2plus_defconfig? Are you trying to force host only mode?
