I just posted a response to Stroller's comments you may want to look at
it.  In summary I found a bug about it
( https://bugs.gentoo.org/show_bug.cgi?id=603472 ) 

aside: Just curious; what kernel was in play when you succeeded? 

I see now that I should have read more of the comments.. apparantly
someone wrote a patch... but as of the end of the commentary on Feb
23,  They still say there is not much to be done until upstream works
on it.

(And since I've found my own workaround...(also in reply to Stroller))
