Subject: zaurus suspend saga: 2.6.32-rc3

Hi!

I'm using patch similar to this for debugging:

...and good news is that it blinks after pressing of power button.

...core > pm_test also works.

I also verified that end of pxa_pm_enter() is reached (with similar
blinking patch). End of corgi_pxa_pm_enter() seems to be reached, too.

Any ideas what to try next?
								Pavel
