Thanks a lot for your post! I installed Ubuntu 16.04 on my Swift 3. But I am only able to boot with acpi=off. acpi=ht also fails. I updated my kernel to 4.9.11-grsec and I followed this post to add missing drivers (http://askubuntu.com/questions/832524/updated-kernel-to-4-8-now-missing-firmware-warnings). What should I do now?
