3.18.34 and 4.7-rc1 are affected too.
The bug seems to have been introduced by "add I/O watchdog for orphan
TDs" (81e38333). I couldn't run bisect because those old kernels don't
build with gcc5+, but I started reverting commits to ohci-hcd.c and
ohci-q.hcd on top of 3.18.34 and got things to work at this point:
