Public bug reported: Just as the title says, the 20.04 and 20.04.1 images use the HWE version of linux-generic resulting in upgrades to the 5.8 series kernel. This seems to effect Ubuntu only, or I should say I checked the Kubuntu, Ubuntu Mate, Xubuntu, and Lubuntu iso manifests which all correctly list linux-generic. Also HWE is not truly complete without the accompanying HWE Xstack.
I checked all the documentation I could find and this was clearly not intentional. In fact the manifest for Ubuntu Focal Beta still used linux-generic, so this got messed up some time between April 3, 2020 and April 23, 2020. Here's just one example of the documentation for kernel support in Focal LTS: https://ubuntu.com/about/release-cycle#ubuntu-kernel-release-cycle Installations performed with 20.04 and 20.04.1 media were supposed to remain on the 5.4 series kernel throughout Focal's 5 year lifespan as had been the case since HWE was introduced. The first step in fixing this needs to be stopping fresh installs of Focal using the 20.04 and 20.04.1 media from immediately upgrading to the 5.8 series kernel. It might be a little tricky to revert users from 5.8 to 5.4, but there have been reports of breakage, particularly concerning Broadcom wifi drivers and some graphics problems. But the graphics problems could also be exacerbated by the lack of the matching HWE Xstack? At any rate it's a bug. ** Affects: ubuntu-meta (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-meta in Ubuntu. https://bugs.launchpad.net/bugs/1911614 Title: Ubuntu 20.04 and 20.04.1 images use linux-generic-hwe-20.04 instead of linux-generic Status in ubuntu-meta package in Ubuntu: New Bug description: Just as the title says, the 20.04 and 20.04.1 images use the HWE version of linux-generic resulting in upgrades to the 5.8 series kernel.
