Description

We’ve seen this a lot especially since we re-enabled the USB tests. Adding a 2nd vcpu to TailsToaster has helped a bit, but not enough.

We currently allocate 52 vcpus + soon 1 for im and 1 for weblate = 54 vcpus on lizard, while we “only” have 48 cores (hyperthreads). There’s a theory that says that overcommitting vcpus is badly supported. So I’ve just shut down 2 isotesters (= 2 * 3 = 6 vcpus) so that we stop overcommitting vcpus. I’ll have another look in a couple weeks and see if this fixes this problem (likely not, but worth trying :) Setting assignee and target version so that I don’t forget about it, but if that fails don’t expect me to fix the other root cause of this problem.

I’ve seen this bug happen today (https://jenkins.tails.boum.org/job/test_Tails_ISO_feature-11832-tor-0.2.8.8/4/) at a time when it was the only test job running, so I think we can discard the overloaded platform hypothesis, and I’ll re-enable the two isotesters.

I’ve seen the I enable more Tails Greeter options step fail in a similar way — both the Yes and No buttons are pressed down, but the Login button is not turned into the Forward button. I strongly expect this issue to be related, so let’s track that here as well for now.

I’ve also seen just the Yes and Forward buttons being stuck + freeze.

  • Assignee set to anonym
  • Target version set to Tails_2.12

Ideas:

  • save journal as artifact when this failure occurs.
  • restart gdm/@tails-greeter@ when this happens.

Have we ever seen this on Stretch with the new Greeter?
