I think I've finally nailed the sucker, and posted a potential fix[1].
It definitely restore my TX1 to a state that is no worse than normal,
so something must be less wrong there. I'm pretty sure that the

to verify/debug that tonight.
Thomas, feel free to squash this into your series or keep it as is, as
you prefer.
