Bug Description

There are (proprietary) reports that the Cannonlake backport for drm/i915 cause some issues on Whiskey Lake systems, like flickering screen and some distracting dmesg spam. Instead of going through the pain of figuring out what else needs to be backported, we'll just drop the backport because there are no products which need it.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
