I meet this FTBFS either. After looking at the code, I think it's caused by this test only waits 5s for writing 134M data. So I changed the time to 180s which I think sufficient for most disks. https://anonscm.debian.org/cgit/pkg-go/packages/golang-github-boltdb-bolt.git/commit/?id=e989709
Since the upstream is not active now, I haven't reported it to upstream. Thanks Shengjing Zhu
