Hi,

My openSUSE Factory installation was taking at least 60 seconds longer than
normal to boot. The delay always occurred on every boot. The delay occured
before initializing the display manager with a message:

"A start job is running for", and it would alternate between four different
services: X display manager, Avahi, NetworkManager, and Modem Manager. 

I tried disabling the Modem Manager service, but it still kept hanging on Avahi
and NetworkManager. I eventually tried disabling and later re-enabling the
NetworkManager services, and it now boots quickly without hanging.

I don't really know why this happened or what I did to fix it. Please let me
know what additional information you need to prevent this bug from happening.

Thanks a lot!
