Hi Jason,

This regression was recently introduced by Linux kernel commit:

commit 16ecba59bc333d6282ee057fb02339f77a880beb
Author: Benjamin Poirier <address@hidden>
Date:   Mon Nov 9 15:50:19 2015 -0800

    e1000e: Do not read ICR in Other interrupt

We tested on slightly older kernels and did not notice it. Next version of our 
patches will contain a fix for this.

Thanks for testing,
