The whiole bisect log seems to dig around in unrelated places so at best
it just narrows the window by adding some known-bad data points.

It gets stranger and stranger - my old 4.7 image worked fine, freshly compiled 4.7 exhibits the same problem. Toolchain has not changed, that I know for sure. What may have changed is kernel .config. My old conf was with whatever I had during 4.7. Then I upgraded to 4.8-rc3 and then 4.8 and selected values for "make oldconfig" new entries. Then went back to 4.7-rc1 and then to 4.7 with this config, answering quiestion about new options when any appeared. Diff is not available since I do not have the old configs archived.
