Comment 22 for bug 1996092

Thank's Kai-Heng Feng.

I know that but if I upgrade ubuntu it could brick MacBook boot and i will never boot again (without hardware repair).
But your proposal give me an idea: kernel upgrade without system upgrade.

So, I look for and install newer kernel and it works !!!
(sudo dpkg -i *.deb)
NOTE: 5.4.0-135.152 kernel is used in ubuntu 20.04

ALTHOUGH, MY POST wanted to report that issue with the latest kernel patches in linux-image-4.15.0-xxx kernel series and if you should consider some patch regression about that.
