Comment 1 for bug 1928744

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command only once, as it will automatically gather debugging information, in a terminal:

apport-collect 1928744

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Note: you may have issues with this, as you've changed the package to the HWE kernel (kernel 5.4 for 18.04) but your details imply you're using 18.04's GA kernel of 4.15 (Ubuntu 16.04 using HWE uses the 4.15 kernel)

If you have issues; please change the package to 'linux' then try apport-collect again.
