Not going out of suspend after "enable_off_mode"

Hi,
I'm having trouble going out of suspend with 2.6.32-rc5 from the linux-omap-pm branch. The board is Beagleboard and u-boot is: U-Boot 2009.11-rc1-00019-g0f36527.

root@beagleboard:~# echo 1 > /debug/pm_debug/enable_off_mode 
root@beagleboard:~# echo mem > /sys/power/state 
[   58.611358] PM: Syncing filesystems ... done.
[   58.635559] Freezing user space processes ... (elapsed 0.00 seconds)
done.
[   58.643280] Freezing remaining freezable tasks ... (elapsed 0.00
seconds) done.
[   58.651245] Suspending console(s) (use no_console_suspend to debug)

After that the board can not be waken up using the rs or "user" button. Suspending without "enable_off_mode" is resuming ok. Any suggestions what to look for?

Thanks
