Just the kernel WARNING traces for one wake-up

Description of problem:
I'm getting a kernel WARNING for each CPU, every time my netbook wakes from suspend.  ABRT refuses to file a bug because it wrongly detects the kernel as tainted, after the warning produced by the first CPU.  Please see the attached warning.txt or dmesg.txt.  I'm using tuned with the powersave profile (USB autosuspend enabled), but it is also reproducible with the balanced profile.


Version-Release number of selected component (if applicable):
kernel-4.6.4-201.fc23.x86_64

How reproducible:
It happens every time the system wakes up with kernel 4.6.4.  I cannot reproduce it at all with kernel-4.5.7-202.fc23.x86_64 despite numerous attempts.

Steps to Reproduce:
1. Reboot the system for a clean state
2. Use Fn-F1 to trigger a suspend, or wait some minutes until the system sleeps.
3. Press the space bar to wake it up.

Actual results:
Each wake-up produces two WARNING traces, one for each CPU (single-core Atom processor with hyperthreading).

Expected results:
No WARNING messages from the kernel on wake-up, just like with 4.5.7.
