Re: Trying to make headway into finding the Xid crashes source...
Do you all still have this crash if you change the 2d and 3d speeds in thee nvidia bios to be equal? I have seen improvement (far fewer crashes) as soon as I got the NiBitor nvidia bios editor and fixed my bios.
I initially had a bios on my XFX 6600GT that had 3d speed set at 500 and 2d set at 300. I switched to 300 at both and now I have stability (relative).
I also notice that my device is running with
vChaim:~# cat /proc/driver/nvidia/agp/status
AGP Rate: 4x
Fast Writes: Disabled
Does this help ?
