--- Comment #19 from Zoltan Boszormenyi <[email protected]> ---
I have tested the released 3.10.1 plus an extra patch from

https://lkml.org/lkml/2013/7/11/661

to avoid the regression mentioned on LKML with suspend in

http://marc.info/?t=137380792100003&r=1&w=2

That happened with this machine, too.

I tried both with and without PM_RUNTIME being set and both kernels gave me the
same result: the first suspend was successful but the second one resulted in an
immediate resume.

dmesg for the "PM_RUNTIME not set" run will be attached. It contains the
warning messages mentioned previously in
https://bugs.freedesktop.org/show_bug.cgi?id=65497 , I think the two problems
have some common root.

I have also tested (or tried to test) these below with and without
CONFIG_PM_RUNTIME.

- 3.11-rc1 plus the ext4 fixes landed in GIT very soon after rc1
  plus the above patch
- linux-next branch from the linux-pm repository from
  git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git
  As of writing this, this branch contains 3.11-rc1 plus some fixes including
  the above patch.

The result in each configuration is similar to the above mail with the
described regression. After "echo -n 'mem' >/sys/power/state" the machine seems
to go into suspend but the power LED stays lit and cannot be resumed by
pressing the power button. Pressing the power button for 4 seconds can turn the
computer off.
