Okay, a quick update.  Just tried with a different .config, and can
reproduce the following build problem with patch 2 of the IO wakeup
series, in code that is later removed by patch 6:

arch/arm/mach-omap2/pm34xx.c: In function 'omap_sram_idle':
arch/arm/mach-omap2/pm34xx.c:281:4: error: implicit declaration of function 'omap3_reconfigure_io_chain'

That's my mistake and I will correct it here and send a new pull request, 
once we figure out what's going on with your boot hang.

I just booted the 'io_chain_devel_3.5' branch from 
git://git.pwsan.com/linux-2.6 on a 35xx ES3.0 BeagleBoard with no 
problems.  Could you please try booting this branch on your OMAP3EVM?
