reply to myself after reading the release notes more carefully:

3.6.1 Minimum hardware requirements #

openSUSE Leap 16.0 requires hardware to meet requirements on these
architectures:

    For AMD64 and Intel* 64 systems: Microarchitecture level x86-64-v2
    or higher.

so I guess incompatible hardware, due to old processor. So will need to
replace a few servers here unfortunately or quit using openSUSE ?

some harsh requirement, considering 32bit CPU were supported much
longer, than x86-64(-pre-v2) :-(
