Hello, FYI I upgraded last week my linux-image-amd64 package to the version from stretch-backports, and I did not experienced anymore the reported issue involving Suspend-to-RAM and my Dell docking station. So I guess you can close this bug report.
For the record, below are the details of the installed version: $ uname -a > Linux vivace 4.18.0-0.bpo.1-amd64 #1 SMP Debian 4.18.6-1~bpo9+1 (2018-09-13) > x86_64 GNU/Linux $ aptitude show linux-image-amd64 > Package: linux-image-amd64 > Version: 4.18+98~bpo9+1 > State: installed > Automatically installed: no > Priority: optional > Section: kernel > Maintainer: Debian Kernel Team <debian-kernel@lists.debian.org> > Architecture: amd64 > Uncompressed Size: 17,4 k > Depends: linux-image-4.18.0-0.bpo.1-amd64 > Provides: linux-latest-modules-4.18.0-0.bpo.1-amd64 > Description: Linux for 64-bit PCs (meta-package) > This package depends on the latest Linux kernel and modules for use on PCs > with > AMD64, Intel 64 or VIA Nano processors.
