on my PC=Dell latitude E6510, RAM=8Gb, GPU=GT218 NVS 3100M, CPU=i7 Q 720 @ 1.60GHz, OS=opensuse 13.1 KDE= 4.13.0
it is already happened but I changed to nvidia drivers, I came back to nouveau and at a certain point everything freezes, but mouse, no possibility to ctrl+alt+F2 or other operations, only hard shut down works, looking at the logs I found this at the tme it happened...
