In the Fedora13 Kernel Source there is an issue with the Intel AGP driver that does not
allow the X server to start on some Sandybrige platform. The issue has been solved in the
Vanilla 2.6.35 according to the commits inline below and as consequence also in the latest
updated Fedora14 kernel.
http://www.spinics.net/lists/stable-commits/msg08831.html
http://www.spinics.net/lists/stable-commits/msg08832.html
http://www.spinics.net/lists/stable-commits/msg08833.html
For compatibility and reliability reasons we are working on Fedora13 and we would like to
have such changes included in the Fedora 13 Kernel Source as well.
Is it possible to have it integrated in the Fedora13 branch?
When is the expected release date?
Thanks and Regards
Gabriele Paoloni
Find inline below the patch generated against the Fedora13 2.6.34.7 Kernel
