I started a Tumbleweed image from
ARM-JeOS-raspberrypi2.armv7l-2018.01.20-Build1.1 and regularly updated it using
"zypper dup --no-recommnds" to the latest version. A bluetooth dongle is
present in the system. During its lifetime it halts regularly, after days
without a problem. Power off and on again restores a working system for a few
days. Most of the time there is nothing in the journal to indicate the cause of
halting the system. Messages do not appear anymore in the journal.
A few days back I found the following:

I have another Raspberry Pi2 system starting with the same image and also
regularly updated with "zypper dup --no-recommends", which never did halt. Only
this one does not have a bluetooth dongle.
