I have installed Debian Stretch (9.6) on UEFI-based platform
Everything went fine, but I cannot... boot to the system.
After the GRUB2 starts the image all I get is:
Loading Linux 4.9.0-8-amd64 Loading initial ramdisk ...
and it freezes...
Once I go to UEFI and enable CSM (The Compatibility Support Module) it is possible to boot to the Debian.
However I don't want this CSM enabled (it adds startup overhead).
What is the actual cause of system not booting without CSM? I'm guessing it is the distro and the only thing is to try
Do I have some other options to boot Debian 9.6 without CSM (legacy)?
