My system: OpenSUSE Tumbleweed.
My hardware: Toshiba A200-209 laptop
http://www.toshiba.eu/discontinued-products/satellite-a200-209/

The system worked properly with kernel 4.8.14-1-default. I updated the kernel
to the latest current version for Tumbleweed: kernel-default-4.9.0-1.1.x86_64
(http://download.opensuse.org/tumbleweed/repo/oss/suse/x86_64/) and
kernel-default-4.9.0-2.1.x86_64
(http://download.opensuse.org/repositories/openSUSE:/Factory:/Update/standard/x86_64/).

Every time when I try to start the system, the kernel does not boots, but
immediately automatic reboot (before loading GRUB2). Booting stops (hangs) on
���Loading initial ramdisk��� and kernel 4.9 does not boot. Only kernels older than
4.9 work.

I tried to install the kernel-default-4.9.0-3.1.gf4d3acd.x86_64
(http://download.opensuse.org/repositories/Kernel:/stable/standard/x86_64/),
but the situation every time is the same.

Reproducible: Always.

Anticipating possible questions: (1) Yes, I used the option zypper ref, zypper
dup. It does not help. (2) journalctl: the lack of any logs (I do not see
anything). Removing the ���quiet��� option from GRUB2 did not help. No information
or logs.
