Description Adam Moerschell 2005-10-20 20:41:38 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4

Description of problem:
On x86_64 architecture, NVIDIA driver version 7676, and I am assuming all future versions of the NVIDIA graphics driver require kernel 2.6.11 or higher.  Currently RHEL4 is not using 2.6.11 or higher.  The exact error is an accounting error with change_page_attr.  The driver still operates under RHEL4, but there still problems that can arise.  For more information go to Appendix L in:
ftp://download.nvidia.com/XFree86/Linux-x86_64/1.0-7676/README.txt

Since graphics applications and graphics development in Linux are an important area, I think it is pertinent to upgrade the RHEL4 kernel.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Attempt to install the 7676 NVIDIA driver on RHEL4(with offical kernel from Redhat) to see the warning from NVIDIA.

We've backported the relevant changes to the rhel4 kernel. 

For the 7676 driver please use: NVreg_UseCPA=1. This will force the nvidia
driver to use the correct interface, and the driver should print no error
messages. The nvidia driver > 8163 should detect that the kernel already has the
fixes and just work properly.

Please re-open if you have further questions.
