The test failures are: armhf: 86, probably all #924036
i386: 1, TestDFM_Approx.test_smoothed_measurement_disturbance out of tolerance: suspect rounding error (x87 extra precision).
arm64, ppc64el, s390x: the same 3, base.tests.test_penalized.TestPenalizedPoissonOraclePenalized2*: looks like a "find which input variables do something" test is finding 3 when there are 4. This is the kind of task where too-weak real signals can legitimately be missed in the noise, but the test input doesn't seem that close to this edge: on amd64 it works for mod.pen_weight *= approximately 3 to 11 (the test uses 10). There are also convergence warnings.
This may need discussion with upstream.
