Hi,

[Adding linux-pm and linux-kernel mailing lists to CC.]

You can try using the pm_test framework for debugging this, to a certain
extent. See Documentation/power/basic-pm-debugging.txt for details on how
to use it.

Also, if you could post any logs that indicate the problem, that would
be great!

Thanks,
Srivatsa S. Bhat
