after that, reboot. You should be back to kernel-default-4.12.14 running. I am doing that as well, so that will take some time to run.
I will continue with plan C proper after my lunch and siesta.
Bad news: Masaru Nomiya wrote that the kernel config file does not contains an entry for the mkiss module, and I confirm that.
I will try to build the module following a modification of what he sent on his script, and see if I can load that module.
Open a terminal, and "su -".

You should have that version.

Notes:
a) Purists will say that it is wrong to do this as root. Well, it happens that none of the above runs as user, because of the ownership of the files. Doing as user is more complicated, so I will not.
b) I never run "make cloneconfig" on the SUSE kernel. I was told long ago to never do it. The *openSUSE* kernel rpm is installed as clean as it should be.
Firs, I recreate the source tree: rpm --erase rpm --erase --nodeps kernel-devel-4.12.14-lp151.28.48.1.noarch delete what remains of directory /usr/src/linux-4.12.14-lp151.28.48 Install them again from local copy: rpm --install /data/storage_c/repositorios_zypp/15_1/repo-update/noarch/kernel-devel-4.12.14-lp151.28.48.1.noarch.rpm /data/storage_c/repositorios_zypp/15_1/repo-update/noarch/kernel-source-4.12.14-lp151.28.48.1.noarch.rpm Ok, I will try to do it as user in a local build directory. In my case, "~/tmp/kernel", which is empty.

Lets copy the instructions from "/usr/src/linux/README.SUSE" here: BUILDING ADDITIONAL (EXTERNAL) MODULES ... (1) by configuring the kernel sources in a separate build directory (see HOW TO CONFIGURE THE KERNEL SOURCES), or Which we just did. (2) by using one of the standard configurations in /usr/src/linux-obj/$ARCH/$FLAVOR, or (3) by creating a Kernel Module Package (KMP) as described in the Kernel Module Packages Manual, https://drivers.suse.com/doc/kmpm/. The first method involves the following steps: (1) Install the kernel-source package. (2) Configure the kernel, see HOW TO CONFIGURE THE KERNEL SOURCES. Done. (3) Create files required for compiling external modules: ``make prepare'' and ``make scripts''. Done. (4) Compile the module(s) by changing into the module source directory and typing ``make -C $(your_build_dir) M=$(pwd)''. Let's try. cer@Telcontar:~/tmp/kernel> cd source/net/ax25/ cer@Telcontar:~/tmp/kernel/source/net/ax25> pwd /home/cer/tmp/kernel/source/net/ax25 cer@Telcontar:~/tmp/kernel/source/net/ax25> Now, what is "my_build_dir"? "/home/cer/tmp/kernel/"? It fails: cer@Telcontar:~/tmp/kernel/source/net/ax25> make -C /home/cer/tmp/kernel/ M=$(pwd) make: Entering directory '/home_aux/cer/tmp/kernel' arch/x86/Makefile:136: CONFIG_X86_X32 enabled but no binutils support mkdir: cannot create directory ‘/home/cer/tmp/kernel/source/net/ax25/.tmp_versions’: Permission denied WARNING: Symbol version dump ./Module.symvers is missing; modules will have no dependencies and modversions.

It is trying to write to "/usr/src/linux", not to my build directory... So what is the incantation, following the readme.suse method one, and a user, not root, directory and permissions? STUCK. (5) Install the module(s) by typing ``make -C $(your_build_dir) M=$(pwd) modules_install''. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)
