If so, then please provide a bug report with reproduction steps.

Thanks,

This is a known problem; please see http://www.nvnews.net/vbulletin/show...27&postcount=4 for a patch that resolves the crash.

Re: bug in nvidia kernel module (pageattr.c:156)
 

Is this AGP patch for all kernels? We're using 2.4 (RedHat 3.0)

Re: bug in nvidia kernel module (pageattr.c:156)
 

Yes, the problem isn't specific to a certain Linux kernel version, nor is it specific to AGPGART or NvAGP.

Just to confirm.....

I'd start doom3, quit, and upon launching a second instance, my computer would freeze...here's some relevant info:
After ssh'ing in I could collect the following info from my logs:
Attached is the nvidia-bug-report file...that utility would not run, however, after a crash...it just froze after printing only a few lines....

So I applied the patch NVIDIA_kernel-1.0-8174-1432714.diff.txt and reinstalled the driver...all is well so far. I haven't been able to reproduce the crash.
