We have a board with OMAP3530 (based on BeagleBoard C3), but with PWRON 
connected. I want to be able to put the board in suspend and shutdown 
from sw, and make it wake when it senses PWRON.

Currently I compile my own Angstrom-rootfs with OpenEmbedded, and 
therefore run the linux-omap-psp 2.6.32 kernel from 
git://arago-project.org/git/projects/linux-omap3.git.

By default the powerbutton worked, but pressing for 8 seconds did 
nothing. I pulled in some twl4030_scripts and setup from a TI Android 
Kernel with working powermanagement (patch attached), and that got the 8 
second reboot working, but I don't know how to get suspend/wake/shutdown 
working.

Suspend:
The following was output in my serial console:

root@board1:~# echo mem > /sys/power/state
[ 4042.726776] PM: Syncing filesystems ... done.

Then I pressed Ctrl-C and got some more output:

^C[ 4046.452270] Freezing user space processes ... (elapsed 0.01 
seconds) done.
[ 4046.478424] Freezing remaining freezable tasks ... (elapsed 0.01 
seconds) done.
[ 4046.501892] Suspending console(s) (use no_console_suspend to debug)

I tried using no_console_suspend, and saw a crash in mmc_suspend_host 
(attached).

Shutdown:
The patch gives me "pm_power_off = twl4030_poweroff", but I don't know 
how to shutdown my board in a way that would cause this function to be run.


And that's pretty much where I am now. I've collected some pieces of the 
puzzle, but I'm not entirely sure it's the right puzzle. Should I be 
able to achieve my goals with this kernel? If so, what's missing/wrong?
