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!
