> Which kernel version are you using?

I tested Linux 5.4 from mainline PPA on Ubuntu 19.10.

Upon further testing I found that Linux 5.4.20 from mainline PPA does boot on this laptop (albeit without working keyboard due to this bug) but kernels from focal repository doesn't: Bug 1863939

As kernels from focal repository does not boot I can not use apport for collecting information; apport error message:

> It appears you are currently running a mainline kernel. It would be better to report this bug upstream at http://bugzilla.kernel.org/ so that the upstream kernel developers are aware of the issue. If you'd still like to file a bug against the Ubuntu kernel, please boot with an official Ubuntu kernel and re-file.

But the thing is - for now only mainline kernels works on this laptop, not Ubuntu kernels. What to do next?
