Subject: PROBLEM: 2.6.29.2 - AGP doesn't work anymore on my nforce2
[1.]
PROBLEM: No more agp card functionality with the patch 2.6.29.2 of 'a/drivers/char/agp/generic.c'
[2.]
I compiled the kernel 2.6.29.2 with my .config of 2.6.29.1 and run into problems with the speed of my ATI RADEON 9600 (rv350)
The following output was generated with my reverted patch of 'a/drivers/char/agp/generic.c':
[4.]
# cat /proc/version
Linux version 2.6.29.2-kmt-1 (root@...LIN) (gcc version 4.3.3 (Debian 4.3.3-8) ) #4 Thu Apr 30 02:19:59 CEST 2009
