Unfortunately, the leaks supposedly stored in that file are not shown
either.
The problem is still present with Linux 5.0. Do you have an idea, how
to fix this?
Have you identified a previous version that works properly?
It seems to have worked with Linux 4.18-rc4+ [1].
If so, have you been able to bisect the problem?
No, sorry, I have not. I do not have resources for this.
Kind regards,
Paul
