After upgrading from 6.3 to 7.0, I launched xorg which crashed the kernel. After looking in the kernel core dump, I found that the agp_nvidia_flush_tlb function of /usr/src/sys/pci/agp_nvidia.c crashed on the line 377. The loop fails from the beginning (when i==0). I commented out the two last loops and it seems to work now but as I didn't understand what is this code for, I'd like to have some explanation about it and want to know if someone got the same problem.
