Boot stops at "Starting command Scheduler"

Hi guys, I've done a fresh install of opensuse 13.1 and everything was fine, so I decided to switch to tumbleweed and following the normal wiki procedure I've done too many times (so disabling old repo, adding the new ones with one-click install and zypper dupping) I've updated my system.
After the reboot I get stucked at:

"starting command scheduler" and there's nothing I can do, only manually reboot.

Thanks in advance for the help
