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. > As far as the crashes go, I don't think I have an OMAP3EVM, but I'll take > a look here on the OMAP35xx boards that I do have. 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? - Paul Uncompressing Linux... done, booting the kernel.
