Either test depends on whether you find it worthwhile to more
specifically identify the root cause. If not, no need to run the tests
on my behalf. I understand that these are time consuming.

I *would* like to really understand the root cause.
And a month ago I would have absolutely gone through
a bisect process so I could narrow it down.

But at this point I'm content to have it fixed (fingers
crossed) and am more interested in putting all this
behind me. It's taken a lot of time and attention.

And even though this represents a real bug, at least
for now I am content to keep all this work in net-next
rather than isolate the specific problem and try to
back-port it (without all the other 20+ commits that
preceded these) to the net branch.

So although I see the value in identifying the specific
root cause, I'm not going to do that unless/until it
becomes clear it *must* be done (to back-port to net).
