Hey William,
My validation hasn't be able to recreate the dereference on v4.1.x, v4.5.x or net_next. Where exactly did you place the two line script in your rc scripts. Our validation was able to run it as soon as ~14 second after the first boot message logged in dmesg. Is this anywhere close to where you were executing it? Likewise he has attempted running at both run level 3 and 5 in case that changed any of the times of how soon the rc scripts are executed. So the more detail you can give of setup the more it might help us recreate what you are seeing.
Thanks,
-Don Skidmore <donald.c.skidmore>
