No, I didn't find any way to trigger the problem on purpose. 295.71 driver (current version) doesn't work right away after start but doesn't freeze OS. Older 285.05.09 version appears to work fine for a long while (1-2 days), then freezes OS. I am pretty sure anybody will see the problem if they try this version of driver with 9400 GT card. > If you can demonstrate that the various nvidia drivers are broken > in various ways, submit a problem report to whoever wrote the drivers > (Nvidia presumably).

I did send the bug report to NVidia's address freebsd-gfx-bugs@nvidia.com. So far no response. I am not sure how such one way, secretive, PR handling works in general for any product. So not sure how NVidia can manage it. No way to track the issue with NVidia. Yuri
