Hi All,
This is my first interaction with the list - hope this is the right place for this question!
I recently installed Fedora 10 onto a development machine, and updated the kernel to 2.6.27.19-170.2.35.fc10.i686
During development of a C++ application for this machine, I was required to update and rebuild the Intel Graphics Driver for XOrg in order to fix a problem with the version of the driver I had. As I understand it, the latest version of the Intel Graphics Driver uses libraries that have been moved into the kernel with version 2.6.28.
I therefore downloaded the source for Kernel 2.6.28.6, rebuilt the kernel and the graphics driver, and fixed the issue with graphics I was having.
Unfortunately, I now have the situation when using the Vanilla 2.6.28.6 kernel results in extremely slow burn speeds when writing to DVD-RW Drives. Where I previously had average burn speeds of 10-11x, I now have average speeds of 2.2x. Since this is core functionality for the C++ application I'm developing, it's something of a problem.
My question is: Is it possible to apply the Fedora-specific patches for my Fedora Kernel (I have the source code for 2.6.27.19-170.2.35.fc10.i686 ) to the Vanilla 2.6.28.6 kernel in order to see if this fixes my drive speeds?
If so, how do i go about this?
Thanks for any help in advance,
FYI, there's a 2.6.29 kernel in updates-testing, you may want to try that rather than building your own.

The kernel doesn't provide libraries for the X server or 3D. It could be the newest X needs a newer version of the kernel 3D code.

I don't believe it has any changes in that area.
The windows world way of trying to sort a problem by randomly swapping versions of components until it runs is probably the wrong way to solve this one.
If your CD drive is running slowly check your kernel configuration is correct and you have the correct libata drivers enabled. Check the boot messages (dmesg) and see what modes are being selected and which driver used.
If that doesn't solve the problem then following up here further with some actual detail (controller type, cd type, section of boot messages etc) has a better chance of making progress.
