[Bug 2062120] Re: lenovo yt3 kernel support

If Ubuntu Mantic with 6.5 kernel works for you but fails in Noble with
6.8 kernel, then something must be broken between these two versions. In
order to identify when the bug was introduced, please download the test
kernels (*.deb) from the following two locations, install the debs, and
then boot to them and see if they work for you or not.

1. https://kernel.ubuntu.com/mainline/v6.6.30/amd64/
2. https://kernel.ubuntu.com/mainline/v6.7.10/amd64/

You can download them to a folder, then run 'sudo dpkg -i *.deb' to
install. Detailed instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If your laptop has secure boot turned on, you need to disable it in BIOS
to use these kernels.
