Bug #886485[1] talks about a hang at boot which may be the same what you are seeing. > 2. How can I revert without losing my working 4.9.0-4-686-pae system?

Most bootloaders, including the default bootloader on PCs (grub), do not use these symlinks at all. To boot with the 4.9.0-4-686-pae kernel by default, you can fiddle around with the grub configuration or uninstall the 4.9.0-5-686-pae kernel. In the latter case you would have to downgrade or uninstall the linux-image-686-pae metapackage as well. Cheers, Sven 1. https://bugs.debian.org/886485
