Since the OP mentioned that Arch isn't stable on his machine, I suspect
that there might be some very exotic hardware involved or that the OP
misconfigured something and for some reasons Debian and Arch are more
sensible regarding to this misonfiguration, than Suse is.
Since the OP installed Arch, the OP is aware what is needed and what not
for the system. I recommend to remove all the services of the OP's
Debian install, the OP doesn't need, resp. to start and stop the same
services the OP's Suse does start and stop.
