Comment # 18 on bug 951548 from Takashi Iwai

Hm, the log doesn't show any delay.

[  117.356037] PM: suspend of devices complete after 476.643 msecs
[  117.357049] PM: late suspend of devices complete after 1.008 msecs

At this point the suspend finished.

Then it resumes:
[  117.358077] pcieport 0000:00:15.1: System wakeup enabled by ACPI
[  117.358447] ehci-pci 0000:00:13.2: System wakeup enabled by ACPI
....
[  118.397519] Restarting tasks ... done.

At this point, user-space is already woken up.  So it took less than a second.
And, the next (and the last) log shows that the system is up, the Ethernet
detected:

[  120.361383] r8169 0000:04:00.0 eth0: link up

That said, from the kernel POV, everything looks good.
