Comment 3 for bug 1634519

The tests (both yakkety and zesty) are still looping, I'm afraid. I didn't see the "BUG soft lockup" in the one instance I was watching. There were no obvious kernel call traces in dmesg, and the test output tail is just:

So this time it seems apt gets killed. The VM went away after that, so I don't have it any more for investigation.

I'm watching another current run and will get its journalctl -f and test output tail, and will then kill the current runs again as there are a lot of them, they loop, and they block large amounts of capacity.
