scotch is acknowledged, Bug#1121516. ppc64el.  Upstream is looking into 
it.
Push come to shove we can skip the failing test if necessary.

opm-grid/opm-simulators is being worked on, Bug#1121356

sundials.  This I don't understand.  sundials is rebuilt successfully, 
7.1.1+dfsg1-10+b1
But the petsc migration test with sundials tests the old version, 
7.1.1+dfsg1-10 not 7.1.1+dfsg1-10+b1
So of course it fails.  Why isn't it testing sundials 7.1.1+dfsg1-10+b1?

feenox. Bug#1121362. The problem is a clash between gmsh and 
opencascade, Bug#1118271, blocked by freecad failure.

petsc will be freed if feenox is removed from testing and sundials tests 
using 7.1.1+dfsg1-10+b1

adios4dolfinx migration tests. Looks like a transient failure not 
related to the transition, it previously passed.
adios4dolfinx test_checkpointing.py appears to be a little flaky, not 
sure how best to manage it
(short of skipping altogether). Raised upstream 
https://github.com/jorgensd/adios4dolfinx/issues/147

dolfinx-mpc. Similar to the sundials petsc problem.  Rebuilt 
successfully 0.9.3-2+b2,
but the dolfinx migration test tests dolfinx-mpc 0.9.3-2+b1 not 
0.9.3-2+b2.
What's the point of the binNMU if it's not being used for transition 
migration?
