A couple of days ago I installed OpenSuSE 12.1 on my laptop after running OpenSuSE 11.4 for quite a while. Upgradeing was no big deal. OpenSuSE has a nice tutorial on that.

The new version finally supports the integrated mobile modem out of the box which is very nice. The only annoyance I got is that the computer does not power off or reboot properly. The system just halts after the last step. I could not find any information on this problem on the net.

Do you happen to know how to fix it or at least how to debug it?
