Hi,all

     I find a strange problem that when our board entered into sleep,from the log ,we found that once the board "sabresd_suspend_enter" then "sabresd_suspend_exit",why? log is following:

[  131.386809] ----suspend_enter----

[  131.387652] ---------max_timeout:0-----------

[  131.387658] power_suspend_late return 0

[  131.387668] PM: late suspend of devices complete after 0.847 msecs

[  131.387675] Disabling non-boot CPUs ...

[  131.388498] CPU1: shutdown

[  131.389154] ----syscore_suspend----

[  131.389292] -----sabresd_suspend_enter--------

[  131.389589] -----sabresd_suspend_exit--------

[  131.389833] Enabling non-boot CPUs ...

[  131.410766] CPU1: Booted secondary processor

[  131.410782] Calibrating delay loop (skipped) already calibrated this CPU

[  131.411156] i.MXC CPU frequency driver

[  131.411203] CPU1 is up

[  131.411800] PM: early resume of devices complete after 0.586 msecs

 

And this log has entered into suspend. You can see maybe it has exit suspend ? why?

 

Thanks~
