I assumed that it was a screensaver related The blinking lights indicate your kernel has encountered a problem it doesn't know how to handle so it panics. Make sure you check your log files in /var/log/* for any helpful information. Otherwise, you'll have to experiment to see how and when you can reproduce the issue which may lead to a better understanding / solution. For instance, it would be informative to see if the problem occurs if you boot into runlevel 3 instead of 5. Good luck, Sean P.S. Any chance you're running with a self-compiled kernel or binary-only module like the nvidia display driver? If so, try running with RedHat / open-source code and see if the problem persists.
