On 5.1-RELEASE and old 5.1-CURRENT, I can use NVIDIA's AGP GART Driver until one or two weeks ago of 5.1-CURRENT, I am not able to use it any longer. It will lock my machine very hard, which only way I can do is turn the power off then boot into single to disable it. Current, I am stuck with FreeBSD's AGP GART driver (agp.ko) with Nvidia and it works great, but the perferomce descrease. NVIDIA's AGP GART Driver = The glxgears will go over 3600 fps. FreeBSD's AGP GART driver = The glxgears will go over 2500 fps. I really have no idea how I can debug, because it only will lock up the machine very hard. ============================ nvidia0@pci1:5:0: class=0x030000 card=0x88911462 chip=0x028110de rev=0xa1 hdr=0x00 vendor = 'NVIDIA Corporation' device = 'GeForce4 Ti 4200 with AGP 8x [NV28]' class = display subclass = VGA ============================ Note: The problem is same on old and new of Nvidia driver, they both behave same.
