Ah, interesting. I talked (privately) with Yann about the
dtv-scan-tables issue early today. We didn't spend much time analyzing
the issue, but there is one side thing that I thought could be causing
issues in the autobuilders:

  https://git.buildroot.org/buildroot-test/commit/scripts/autobuild-run?id=c47d9bf2080e33fa3a87223afd93f46363e36447

This change from Peter Korsgaard adapts the logic in autobuild-run that
removes 5 random tarballs between every build. This exists to force
autobuilder instances to regularly re-download stuff, which allows to
test our download infrastructure.

Originally, DL_DIR was flat, so we were just picking up 5 random files
from that folder. Now that DL_DIR has sub-directories, Peter changed
the logic to be recursive, and pick 5 random files recursively....
except that DL_DIR/<package>/git/ contains a Git repo, and I'm not sure
deleting random files from a Git repo is really recommended.

So I have no idea if the download problems are related to this
autobuild-run issue, or if there are actual issues in the git download
helper, but we should probably fix autobuild-run anyway.

Best regards,

Thomas
