Try putting the following in the Device section of your XF86Config file: Option "ForcePCIMode" "true" That will slow down your 3D acceleration though. I have been running with this option for about 2 days and have not had a lockup with it yet. I was going to run it for another day or so and contact Eric Anholt about it. See if it works for your machines. That should provide enough corroborating evidence. -- Glenn Johnson USDA, ARS, SRRC Phone: (504) 286-4252 New Orleans, LA 70124 e-mail: gjohnson@srrc.ars.usda.gov
