Bug #886485[1] talks about a hang at boot which may be the same what you
are seeing.

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.
