Hi all,
TL;DR: It seems like armv7hl koji builders are locking up, most often
when running dnf to install the buildroot or to install dependencies.
I've seen many people getting hit by this issue:
https://pagure.io/fedora-infrastructure/issue/10833
So, if your build takes unusually long time on armv7hl, look at the
task's logs in koji, and if they're stuck at an early stage of the
build, you will need to cancel the task and resubmit it (or ask releng
to run "koji free-task NNNNNNN" for the stuck armv7hl task).
