Default Random short freezes in 3D, X 1.4.0, nvidia 100.14.19, GF7600GS

Hi,

I'm experiencing random freezes when running 3D applications; be it games (such as Enemy Territory) or glxgears. When the freeze occurs, there's no new information from kernel in dmesg and nothing from X server either.

The difference from working state has been upgrade from kernel 2.6.16.20 to 2.6.22.7, upgrade to latest Debian/Sid and update from nvidia drivers 9631 to 100.14.19.

Personally, I presume the issue arises from the X server upgrade and not the nvidia driver or kernel upgrade, as I face other issues clearly X-related, however, I don't see a way how to figure it out, as the driver interface supposedly changed in Xorg 1.4.0 (7.3).

As a basic mean of remedy, I've attempted to disable AllowGLXWithComposite and explicitely disable Composite extension itself. Other than that, I'm pretty clueless as to what to do - X11 isn't my usual business.

Please, find the attached nvidia-bug-report.log. Any help would be appreciated.

Thanks,
Steve

Just an adition, to be explicit: turning off composite explicitely didn't help at all...

I've been aware of the freeze issue for a while and it is at least partly kernel related.

Using the nv driver, all kernels work.

Using the nvidia driver:

2.6.17.11 is the last kernel version that works without freezeing. I've had uptimes of 60+ days. From 2.6.18 to 2.6.23, I'm getting freezes with ALL the nvidia drivers (from 8xxx up) after an hour or two. Sometimes a few minutes.

No options appear to be influencing the freeze in the kernel settings.

The nature of the freeze: hard lockup, mouse does not move, machine does not respond to ssh or ping. Logs contain nothing, magic sysrq doesn't work, no apparent cpu or harddrive activity.

Motherboard: Asus m2n32-sli with the latest firmware.
GFX: Nvidia 7600GT silent
CPU: AMD Athlon64 3500+
Memory: 2GB Kingmax
OS: Debian/sid


I would love to switch from the 2.6.17.11 kernel to one that supports dynticks, but can't because of the freezes. I'm used to having weeks of uptime and hard lockups after an hour are simply not acceptable for my working environment.

I've included a "sort"-ed list of the last working kernel configuration and the latest kernel I've tried and freezes.

If there is anything I can do - ranging from trying out any kernel patches to custom drivers - let me know. I'd love to fix this issue. I've bought nvidia specifically because I thought they have a better linux driver than ati, but if it crashes much then that might not be the case.

Are you sure it's not a heat-related problem?
What are your GPU/CPU/mb temperatures at?

I know it sounds weird that it would be heat-problem when it has worked perfectly for you in the past.. but fans and heatsinks do grow dust after some time.

Yes, I've got ksensors running and the cpu never goes above 39C even under full load and the motherboard heat sensor is never above 35C.

The nvidia card's own sensor has shown 48 when the freeze happened, so I guess it's safe to say the cause isn't related to the temperature at all. I have never ever seen the gpu temperature go above 60 and that's gpu stress test included.

I'm guessing 2.6.18 introduced some changes that are not in itself a bug in the kernel, but react badly with the nvidia code, since it appears that the problem only manifests with newer kernels and the nvidia driver specifically.
