Description of problem:
When booted from 4.3 kernels, laptop starts killing process for OOM within 8 hours.

Version-Release number of selected component (if applicable):
kernel-4.3.4-200.fc22.i686

How reproducible:
Always, but no hard timeline.

Steps to Reproduce:
1. Boot with 4.3.4 (hang on to last working kernel-4.2.8)
2. Do stuff.  Network seems important
3.

Actual results:
OOM, with userspace memory only 50% used.

Expected results:
Same stable operation as 4.2.8 kernel.

Additional info:
Adding a USB wifi dongle (for a total of 2 connected wifi nets) seemed to cut time to OOM in half.  But this was subjective and squishy.  Haven't done it often enough to quantify.

This is different from https://bugzilla.redhat.com/show_bug.cgi?id=1303270 in that SUnreclaim is not increasing without bound.  However, it is similar in that user space processes don't seem to be using the memory. (And in 4.3 kernel being generally borked.)  I'll be adding logs and another regression for intel video.
