Hi, I'm having some problems with the new
3123 drivers.
After installation of the latest drivers and recompiling my standard benchmarks the system
(X server) hangs after running a few minutes of
heavy OpenGL (Specviewperf 7.0 and own apps.)
These programs run fine on the exact same system with driver releases 1.0--1541,2313,2802,2880, and 2960.
(I've just downgraded again to 2960 to make sure, and everything runs normal).
No abnormalities in boot.log,XFree86.0.log,
messages

Any suggestions where to look/ experiments to try?

Check the SBA status when the new driver is active
by entering on a console

'vi /proc/driver/nvidia/agp/status'

Close vi with ':q!' and "Enter". It's a very good
editor btw..

The old 2960 sets SBA to 'disabled' by default.

Thanks for the suggestions.
The problem appears to be temperature related:
SpecviewPerf crashes the machine if you run it twice within a short timespan.
I've removed the side-panel of the machine and
there is no problem now with either driver.
Time for yet another case-fan...

btw:
here are the results for those who are interested
2960 drivers:
drv: 18.749
light: 6.010
dsmax: 4.003
ugs: 3.587

dx: 18.607

3123 drivers:
drv: 19.205
light: 5.583
dsmax: 4.260
ugs: 3.734
proe: 5.858

I'm curious, do you notice artifacts (like two surfaces the same distance away from you, interfering with each other) on the first few scenes in SPECviewperf?

I'm wondering if that's normal...

Hard to see at almost 20 fps, but I ran the drv-08 test with another heavy app running to slow it down, and you're right: especially in the bright colored surfaces I see triangular artefacts in some orientations of the model. They don't show up in the scene that gets dumped to .png so I missed them initially...
I'm unwilling to re-uninstall the drivers again, but if I get this problem with my real apps (where I do care how the scene moves) I know where to look, thanks for pointing that out.

OK, it's not just me then. ;)

I think it's because of the way the GL calls for that demo are set up; I think there are two surfaces the same distance away from you. So I think it would be normal, assuming everybody sees it and not only me.
