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 http://security.ubuntu.com/ubuntu/pool/main/l/linux/linux-headers-5.4.0-135_5.4.0-135.152_all.deb http://security.ubuntu.com/ubuntu/pool/main/l/linux/linux-headers-5.4.0-135-generic_5.4.0-135.152_amd64.deb http://security.ubuntu.com/ubuntu/pool/main/l/linux/linux-modules-5.4.0-135-generic_5.4.0-135.152_amd64.deb http://security.ubuntu.com/ubuntu/pool/main/l/linux-signed/linux-image-5.4.0-135-generic_5.4.0-135.152_amd64.deb http://security.ubuntu.com/ubuntu/pool/main/l/linux/linux-modules-extra-5.4.0-135-generic_5.4.0-135.152_amd64.deb 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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1996092 Title: Macbook boots with linux-image-4.15.0-192-generic (4.15.0-192.203) but freezes with newer kernels (4.15.0-193.204,4.15.0-194.205, 4.15.0-196.207) Status in linux package in Ubuntu: Confirmed Bug description: I have old MacBook with broken main Graphic Controller (a well-known hardware issue https://discussions.apple.com/thread/251049873 ). So I switch to use Integrated Graphics Controller. I am using Ubuntu 18.04.6 LTS and after an 'apt update' laptop doesn't boot (freeze during boot). I looked for latest updated packages and I found: linux-image-4.15.0-192-generic 4.15.0-192.203 amd64 => linux-image-4.15.0-193-generic 4.15.0-193.204 amd64 So, MacBook boots linux-image-4.15.0-192-generic correctly, but it doesn't boot with newer kernels (4.15.0-193.204,4.15.0-194.205, 4.15.0-196.207) I could not find which change is included in newer kernels that did this issue. How could I support about this issue?
