Hi everyone.

I'm having an issue with a new 10.8 installation and the v1.10.0 r1394 Chimera bootloader.

With GraphicsEnabler=YES, my Sapphire 6870 1024MB loads and is detected. I get a desktop and full resolution, but the system video appears to lock up every few seconds for a split second. What I mean by that is that the display just pauses. Spinners and progress bars pause in place for a split second. The mouse pointer and text input pause. I think you get the general idea.

With GraphicsEnabler=NO, I still get full resolution, but the card is just detected as "AMD Radeon HD 6xxx". In this instance, however, the system is incredibly smooth and there are NO lockups to speak of. Everything works as I expect it to.

System works as expected in 10.7.4 as well, so it is NOT a hardware issue.

Just wondering if I can do anything to help anyone diagnose this.

Thanks!
