I am trying to get a workaround in place for the sleep, resume, auto-
sleep issue, so that is will just wake up on one button press. If I
hold down a WAKE button it will wake up so I figured if I could add my
own lock during the resume sequence it would stay on. This was an
incorrect assumption. I managed to add a wake lock during resume, but
it does not prevent the system from going back to sleep. This same
wake lock will prevent the system from going to sleep in the first
place, so this tells me that holding a WAKE key does not work because
it creates a wake lock, but because it is continuously triggering
something else.

I also found that pressing a WAKE button and feeling the screen works
in most cases. Usually, on repeated failed attempts to wake up is when
it doesn't work.

So, it seems that the device needs constant attention or it refuses to
wake up and we need some way to spoof this.



Below is some of the code that I've tried adding. I've also tried
changing the timeouts in policy/src/com/android/internal/policy/impl/
PatternUnlockScreen.java to no avail.

Ok, I discovered a workaround for this bug over on the android-porting
forum.

Hello fuzzy7k,
do you have integrated that workaround? Is it working? Could you give further detail how you did it?

Yeah, it works. The kernel needs patched with the three lines in the
link before building the image. So, it will only benefit future
releases.

Hello fuzzy,
I patched my kernel with the three lines from the link above for my custom build and have following results:
- I could wakeup from suspend by clicking onetime a key <<Good
- But I could not pass the lock-screen from honeycomb by touchscreen or mouse because no response from both devices <<Not good

Any ideas or advices?

Sort of sounds like your device drivers do not play well with suspend.
Try switching to the terminal and modprobe the drivers for your
devices.

Mmh I think my description was not good. After resuming at least the mouse seems to work because I could move the pointer, but I could not move the icon on the unlock screen.

Which target and kernel are you using? 

Best regards

hm, you are right, I hadn't noticed because it works for me upon the
second tap. It seems part of the original bug is still causing grief.
I say this because taping the screen once or pressing a key after the
initial wakeup key is pressed then allows me to slide the unlock.

It does not work for me at all. I tested tegav2 with the latest code,
my device does not get into sleep. It tried to sleep, but just hang
with a shell prompt. Need to dig more on this, it is still more like a
kernel issue.
