While I'm working on the computer, the monitor sometimes suddenly goes black and it starts outputting lines like below in ~7 seconds intervals.
[ 127.759539] NVRM: Xid (PCI:0000:01:00): 16, Head 00000001 Count 00002a11
[ 135.955830] NVRM: Xid (PCI:0000:01:00): 16, Head 00000001 Count 00002a12
[ 144.148118] NVRM: Xid (PCI:0000:01:00): 16, Head 00000001 Count 00002a13
It goes on forever and I can't really get back to the system unless I reboot the computer.
Once I reboot it everything works fine for a couple of days, but eventually it shows up again.
Does anybody have an idea to what it is and how I can solve this?

. IMHO, this seems a driver problem. Which driver are you using? NVIDIA proprietary or open source one? Latest version? What does it happen if you change driver source?
