The Windows BSoDs and Linux hangups seem to be related (for me).

Linux's driver gets into an infinite loop - hangup.
Windows' driver gets into an infinite loop - BSoD with info about infinite loop.

Those colourful crashes were simillar to Linux's "image damage" - but seems to be fixed on both systems now.

As for nVidia taking the latter issue seriously, I'm not convinced that the fault lies with driver: 6629 worked fine for me up until a certain point, after which 6629 and later drivers would freeze up eventually. I hadn't touched Xorg's config, so nothing changed there.
The thing I'd like to point out is that games work when there's NO AGP SUPPORT. AGPGART and NVAGP both crash the same but no agp support is rock solid with lower framerates.

What I noticed is that a simple application (400fps+) will crash _immediately_ within 2 minutes every time. However perhaps not glxgears for some odd reason.

KDE GL screensavers, gl-117 or a spinning cube demo will all crash the system more reliably than playing a high end game/demo.

I ran a complicated demo using pixel/vertex shaders all night (26fps) at a huge res, no problem. I run gl-117 .. no textures, but 500fps - crash immedately. If I turn on forced 16 anti-alising I can't get it to crash!

Lower fps = survive longer. I tried my 6600GT in a friends comp, it ran doom 3 and crashed after 15 minutes. I ran a KDE GL screensaver and it crashed within 3 seconds.

This could be the reason not using AGP is more stable, since it's simply slower.. and nothing bad seems to happen if you force it to be slower. Q3A is the same thing - it has max fps at 90 - therefore it doesn't freeze. These crashes happen really fast when you're pushing the card at a simple task.

At least in my case, turning off AGP didn't improve the stability of the system.
Can you post your machine configuration?

Asus A7N8X Deluxe motherboard (the 333mhz FSB original w/BIOS updates)
MSI NX6600GT VTD128
Athlon 2700+ XP
1Gig pc2700 ram
x.org 6.8.2

gentoo linux ~x86

I tried enough different theories til I went back to running AGP-less. I' just played World of Warcraft for a good 4 hours straight no crashes. Something's amiss in the AGP section of the driver I tink.

If it wasn't so sad, I'd find it hilarious that the nVidia AGP driver fails on an nVidia nForce2U based board.
BTW, with Xids do you get?

The AGP seems to be one aspect of the problem:
A. Disabling AGP doesn't work on all cases. (Mine for instance.)
B. The nVidia driver is unstable on PCI-E machines. (Which AFAIK should behave just like a normal PCI)
C. If Saulzar is indeed correct, then we are talking about what-seems-to-be a timing problem; Turning off the AGP just reduces the chances of something blowing up, but does not eliminate it. (Which should explain the PCI-E devices failing like their AGP counterparts)

Cheers,

hi,
do you know where this "infinite loop" resides? in the kernel module, in the GL library or in the agp module? if it's not in the gl library maybe it is easier fixable.. of course I'm not a kernel developer so I might saying **** here...

6600GT PCI-E... on AMD64...
It seems like it's "stuck" somewhere in the "bottom half", so yeah, probably a timing issue... (see attached back-trace of the hang)

But unlike "most" people here, my system doesn't hang/crash/... it just freezes for some seconds... but then it gets on the right track back...

Also I get these XID only on for some very special apps (like GL_GAMEOFLIFE (while activating the pbuffer) & BFV (with Cedega in the main menu))...
But doom³ , ut2004, glxgears, morrowind...(and all other games I own/demos I've written) don't have any problems...


GL_GAMEOFLIFE is a part of Nvidia's CG Demos for linux.

My system sometimes "get right back" too....but not so often.

I hadn't have any crash after enabling "Prefetch caching" in BIOS...hope it'll remain as it is :-|

what's that option about? (prefetch caching)
what motherboard do you have?

thanx

I just tried upgrading my mobo BIOS and it didnt help anything :\ Anyway nvidia really needs to get on this, anyone who has this problem should file a bug report.

If it's somehow timing related, this can explain why most of my computers run noramally
within couple of days and few of them "freeze" in couple of hours( With same software
but different CPUs/Main boards).

So "Timing" does hide bugs and I guess the logic flow of the driver is not logical flawless.
In my experience, this kind of bug is really hard to nail down. Hope I am wrong.
