Dear maintainer(s),

Your package has an autopkgtest, great. However, it recently started
to fail in testing on ppc64el. It also has never passed on armel, armhf
and s390x. I'm not sure what to make of all the recent migration run
failures on amd64, arm64 and i386, but the test *appears* to be flaky.

Paul

This seems to have gone away with the latest upload.

But numba now fails everywhere, except on amd64 if run on a very
powerful host (most of our hosts, it times out).

thanks

Upstream never actually fixed this, the issue was just closed
as "stale", which should not count as a fix.

This problem is happening right now as a FTBFS issue.

I'm going to disable the failing test on ppc64el as the least bad option.
(there are other packages waiting for this one to be built on ppc64el).

Thanks.
