Re: x86_64 lock-up problems - any ideas?
Thanks for the glxgears tip. In two days of trying I couldn't reproduce the problem. Using the glxgears tip I can definitely crash the system. I've got a debug trace from the serial port and the nvidia-bug-report.log attached.
It seems that I'm getting a slightly different problem rather than a null pointer dereference, and my machine definitely does hard lock. Furhtermore, I'm not running SMP - I couldn't afford the second Opteron 252 yet.
