The commit that ends up being marked bad is odd, but there it is:
69bec7259853 "USB: core: let USB device know device node".

Very odd, but I tested multiple times: I'm typing this on
d883f52e1f6d, and everything is fine. On 69bec7259853, I can't type.

Note that when I say "I can't type", it's the early boot disk
encryption password.  And maybe there's an oops there, but I can't see
it, and I can't log it.

I don't even have CONFIG_OF enabled, so I don't see what difference
that patch would make. But it makes some difference.

I'll double-check by reverting it on top of current git (it does seem
to at least revert cleanly), I haven't done that yet. But adding the
people involved in that commit to the discussion to see if anybody
sees anything.
