I just went back to a -rc7 kernel (but a largely different .config) and
it did not happen.

I reverted
74b5820808215f65b70b05a099d6d3c969b82689 and
773c0ef52ae8dd375b877c51bc6e8d03fb0b59b7

but still see the same problem.  I will try to build a -rc7 kernel with
a similar config for a fair comparison.  If it works, I'll start a git
bisect.
