My question: Is it possible to run newest Kodi 18 testbuilds with older Kernelversions? If yes: how

Sure - downgrade the kernel in git to whatever version you need then compile LibreELEC.

Edit: you'll need to go back a long way to avoid the bug - it's in 4.9.y: https://www.spinics.net/lists/linux-medi...21356.html
