Sorry for the delay in coming back to you. Can you please confirm if the issue istill triggerable on 7.0.10-1 as in testing? If youes, can you: - Test 7.0.11 upstream? Does this expose the problem as well - Provide fresh logs including the problem. Given 7.0.4 was fine but 7.0.7 had the problem in case you can reproduce the problem with recent kernel still, would you be able to bisect the issue and we can get the breaking change?
