I'm seeing similar issues, and a revert of the above caused the problems to go away. I'm testing on a baseline of net-next as of today (3238a9be4d7a) plus some TIPC patches I was trying to test (which are 99.9% unrelated to this, I'm sure).
Details captured from serial console are below. 100% reproducible.
I can probably try a test/debug patch for you if need be.
Paul.
