It was probably something temporary... It works now.

[Michał Sawicz (saviq)]

Well, we still need to look at it and at least try and reproduce ;)

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Jonas G. Drange (jonas-drange)]

Yeah, seeing this in USS builds as well [1].

Isn't this the "Qt doesn't like the new arm64 kernel" bug we already had that made us revert the kernel?

[Timo Jyrinki (timo-jyrinki)]

The general problem is that the new kernel comes back at each upgrade of the ubuntu kernel, and a custom one needs installation for each. But yes bug #1630906 is still open.

Qt 5.7.1 and 5.6.3 (in March or so) will eventually have upstream fixes that hopefully work fully unlike the cherry-picks that had their own issues in my testing.
