Hi, thanks a lot for the help. I didn't had time to test it, but with the upgrade to the most recent kernel on testing: linux-image-4.18.0-1-amd64 4.18.6-1 amd64 , the problem disappeared. The previous problematic kernels were: linux-image-4.17.0-1-amd64 4.17.8-1 amd64 linux-image-4.17.0-3-amd64 4.17.17-1 amd64 And the last properly working kernel was: linux-image-4.16.0-2-amd64 4.16.16-2 amd64 Sticking to that last one (4.16) I could avoid the issue until the 4.18 was released. Now the problem is solved. Hope this can give some clue about the cause. Thanks again!
