Hey Brendan, Thanks for reporting this bug. It looks like the crashdump files didn't come through?
Could you please try to reproduce with the 5.8 kernel from Groovy on your Bionic install? These are the steps to install it. Please remove the .list file as soon as you install the packages, to avoid other packages from Groovy to be installed unintendly. $ echo 'deb http://archive.ubuntu.com/ubuntu groovy main restricted' | sudo tee /etc/apt/sources.list.d/groovy.list deb http://archive.ubuntu.com/ubuntu groovy main restricted $ sudo apt update $ sudo apt install --dry-run linux-{image,modules-extra,headers}-5.8.0-18-generic $ sudo rm /etc/apt/sources.list.d/groovy.list Once you're done with testing, you can remove the installed packages with: $ sudo apt purge linux-{image,modules,modules- extra,headers}-5.8.0-18-generic Please note there's an additional linux-modules package in this list (which is a pulled as a dependency in the install command.) You can also specify other packages if any are also pulled during the install step, but testing it here it doesn't look like any other packages are pulled in.
