Comment 27 for bug 1886257

@Abhishek,

1. remember to run `sudo update-grub` after modifying grub parameters in /etc/default/grub

2. You may install my test kernel with:

   $ sudo apt install \
       linux-modules-extra-5.4.0-41-generic=5.4.0-41.45+lp1886257 \
       linux-image-unsigned-5.4.0-41-generic=5.4.0-41.45+lp1886257 \
       linux-headers-5.4.0-41-generic=5.4.0-41.45+lp1886257 \
       linux-headers-5.4.0-41=5.4.0-41.45+lp1886257

   You may find package information in this page: https://launchpad.net/~vicamo/+archive/ubuntu/ppa-1886257/+packages

3. When booting, remember to press ESC to enter grub menu and select kernel "5.4.0-41-generic".

4. And, again, need your dmesg to confirm it's actually working.

Thank you.
