Sometimes my system (Ubuntu 14.04 64bit with the latests proprietary drivers from repositories) hangs, artefacts appear on the screen and systems doesn't respond on any commands from keyboard or mouse. I connected to my machine with ssh and run dmesg, output:
[100002.771845] NVRM: Xid (PCI:0000:04:00): 6, PE007e 00dc 00ffffff 00000000 00000000 00000000
[100002.773784] NVRM: Xid (PCI:0000:04:00): 6, PE007e
[100002.775644] NVRM: Xid (PCI:0000:04:00): 6, PE007e 00dc 00ffffff 00000000 00000000 00000000
How to fix this problem? I tried use nouveau, but in this case suspend doesn't work.
