I posted somewhere else as I was not sure it was same bug...
But now I think it's the same
Just I have Xid 23 and 6 only. Even with Gentoo Xorg 6.8.2-r1 (some previous post talked about it). Screen goes uniform color, mouse still here, can even switch workspace and keep going.
I thought it was temperature related as adding extra big fan in front of card help me to stabilize it. But glxgears with even higher temperature does not make crash happen.
Neo2 Platinum - AMD64 3500+ - BFG 6800GT OC (factory OC not extra). Gentoo 2005.0 64bits.
