Hi!

So, Pavel can you re-test? Maybe there can be problem with some driver
which Tony did not compiled into zImage? Just speculation...
I re-tested with today's git, and it seems to boot. Thanks for help...
OK good to hear.

Now. "echo mem > /sys/power/state" is broken, as in "returns
immediately in about 50% cases". The messages are

Powerdomain (per_pwrdm) didn't enter target state 1
Powerdomain (core_pwerdm) didn't enter target state 1

Any ideas? Thanks,
Works for me after enabling the idle timeouts with the following
script and blanking the screen and disconnecting USB:

Also both keyboard LEDs should start blinking after the idle
timeout with screen blanked and USB disconnected. If not, you
have some module loaded that blocks the deeper idle states.
Ok, tried that, I had to do:

 cd /sys/class/gpio
 echo 162 > export
 cd gpio162
 echo out > direction
 echo 1 > value

to get the debug lights to work. But I could not get those leds to
blink.
modprobe leds-gpio
modprobe ledtrig-default-on
Is this actually neccessary/relevant?
echo 255 > /sys/class/backlight/acx565akm/brightness
And this?

Thanks,
									Pavel
