Hi Joachim,
I am sure about properly supported way for SLE12 SP1 ( which I am also not sure if it is not already out of support ).

But if I get it properly, boot process cannot find filesystem, so this means that it initrd missing some module to read it. Do you have module in your initrd to read that perc controller? unpacking only does not help if it is not also included in initrd that is loaded during boot process. So when calling mkinitrd check if all required modules for given perc controller is included there.

If it is there, please write more informations like

which boot failed? when starting installation or after installation when trying to boot target system.

How exactly you inject that kernel module?

Do you already check driver kits documented by SUSE? https://drivers.suse.com/doc/Usage/Driver_Kits.html It specify also how to add additional driver to installation.
