16.5 and all previous versions ran fine on the old PCs i used. 16.6.2 on two different machines hard crashes on reboot. None of the safemodes worked until hand edited.
Editing the grub linux switches to include to " noquiet nosplash nomodeset " lets it boot up successfully. " force-video-safe " may be required for some.
The weird thing is that even after changing /etc/default/grub and rebuilding /boot/grub/grub.cfg, it only fixed the first entry for each kernel, none of the safe mode entries were fixed! May be it is my error, but have never seen this behavior on any other distro, even previous Debian based ones. dracut is not installed, which may break the pipeline of commands?
This only fixes the first grub bootup entry, but does not change the various safe video mode grub boot up menu options so none of the safe-modes work:
Only two entries out of ten were actually regenerated with noquiet OR nosplash. To make it easier to read, some parameters were removed like the actual UUID, ramdisk size, etc.:
Six grub boot entries did not have nomodeset:
