grub.cfg

After an Upgrade from Leap 42.3 to Leap 15 the new Kernel versions are not able
to boot the system. The old kernel (kernel-default-4.12.14-lp150.10.2.x86_64)
which was still available after the upgrade works without a problem.

Meanwhile I did several package updates and are now on kernel
kernel-default-4.12.14-lp150.10.2.x86_64 for the new ones. None of the 4.12.X
kernels I tried worked.

The system is a test installation within a Virtual Box VM. It was installed
with a previous Leap version and upgraded before to 42.3.

The filesystem is btrfs.

In failure case the boot stops after:
