Hi Peter,

I'm suspecting a makefile bug in Linux kernel that makes build process 
unreliable.  It seems there's a missing dependency between 
latent_entropy_plugin.so and generated/utsrelease.h header.

I'm continuing to investigate this, but, meanwhile, [1] should fix spamming of 
upstream developers.
