I get sporadic hard lockups when using OpenGL accelerated apps with ati-drivers-8.452. I've had similar problems with other versions, but it's hard to pin down exactly which versions because some releases caused other critical problems and I've upgraded and downgraded many times. I've experienced this problem in particular with games-sports/xmoto, but I also remember in particular having x11-misc/googleearth-4 cause hard lockups with an older ATI driver. My card is a Radeon 9600 SE (RV350 AQ). If it matters, I have an nForce3 AGP chipset and I'm using Opteron on-CPU agpgart support from the kernel.

Bugs in binary stuff need to be reported upstream and not to Gentoo, sorry.
