2.4.20-27.9 kernel upgrade killed my 3D performance


Has anyone on RedHat 9 seen an issue with 3D graphics performance after moving from kernel 2.4.20-24.9 to kernel 2.4.20-27.9?

I have a Radeon 9500Pro and installed the 4.3.0-3.2.8 ATI drivers when I was running kernel 2.4.20-24.9. Tux racer and Chromium worked great. I recently moving to the 2.4.20-27.9 kernel and now the 3d performance is incredibly choppy. I tried to reinstall the ATI drivers but the sytems says that the driver is already installed. I ran fglrxconfig but no change in 3D performance. If I boot the old kernel, the 3D performance is fine. Does anyone have some suggestions?

Also I have a ATI TV wonder VE. I was using tvtime to view TV on my systems by doing the following (when running kernel 2.4.20-24.9)
modprobe bttv
tvtime&

After the kernel upgrade "modprobe bttv" fails with a module error. Do I have to do the "make module" and "make module_install" part of kernel building to build/install the modules for the new kernel?


Thanks,
Nate

boot into the old kernel, and uninstall the problem areas, and boot into the new kernel and install them fresh again....this stuff was compiled for the old kernel, so that more so the reason why its not working for the new one...typically you'd just install again, but if your saying that its saying its already installed, then try uninstalling these things in the old kernel, and like i said, just install again.

I did the following in the new kernel and the 3D acceleration performance was restored.

rpm -ivh --replacepkgs fglrx-glc22-4.3.0-3.2.8.i586.rpm

Thanks,
Nate

Package Already Installed

If the package of the same version is already installed, you will see:

Preparing... ########################################### [100%]
package foo-1.0-1 is already installed

If you want to install the package anyway and the same version you are trying to install is already installed, you can use the --replacepkgs option, which tells RPM to ignore the error:

rpm -ivh --replacepkgs foo-1.0-1.i386.rpm
