It might be something in your xorg setup that is triggering it. FWIW, I have also seen seemingly identical symptoms a couple times on a Debian server I set up a couple weeks ago at work, also using a Radeon card (Radeon 9250) and xorg. The console goes away (freezes completely), Control-Alt-Backspace doesn't work to restore it, but the system is still accessible via ssh. This leads me to suspect the reported problem may not be a FreeBSD issue per se but an xorg Radeon driver issue. Reducing the maximum sync setting may have helped, but I don't consider it confirmed yet. -- Clifton -- Clifton Royston -- cliftonr@iandicomputing.com / cliftonr@lava.net President - I and I Computing * http://www.iandicomputing.com/ Custom programming, network design, systems and network consulting services
