Rather than compiling a kernel, you can use a pre-compiled version released by Ubuntu. 3.16 kernel chain is supported and it might suit your needs.
In your browser address bar paste this: http://kernel.ubuntu.com/~kernel-ppa/mainline/.
- Use Ctrl+F to bring up search.
- Use
3.16as a search string. - Tap PgDn key until the screen changes to the image below.
Notice how 3.16.60 was just compiled on November 6, 2018 by the Ubuntu Kernel Farm. Click on 3.16.60 link and this screen appears:
Click the links under AMD64 to download:
- linux-headers-3.16.60-031660_3.16.60-031660.201810220732_all.deb
- linux-headers-3.16.60-031660-generic_3.16.60-031660.201810220732_amd64.deb
- linux-image-3.16.60-031660-generic_3.16.60-031660.201810220732_amd64.deb
Change to your downloads directory:
cd ~/Downloads
Keep repeating command until all three files are downloaded with right size:
$ ll *.deb

AFTER missing module is installed, kernel 3.16.60 installation carries on where it left off.
Booting with 3.16.60 works OK for me but I loose:
- Kernel features for NVMe M.2 SSD Gen 3.0 x 4 suspend / resume.
- Kernel features to set laptop display brightness to last setting.
- nVidia display driver features.
- Support for Thunderbolt Type C DPI to HDMI converter is lost.
-
Grub overrides are needed to avoid login loop. Ctrl+Alt+F1 needed to access console.
