X freezes machine. mouse moves, ssh working
 

X keeps freezing randomly. Numlock wont respond but mouse cursor and button shutdown work. I can ssh into the machine and when I "ps aux" X shows about 20-22% cpu usage. I tried killing a bunch of things but nothing would bring it back except a reboot. I have a Nvidia gf4 ti4200 8x on a hp i820 camino 4x,2x agp bus. I have agpgart drivers built into 2.6.11.6 kernel. I was using the "nv" drivers with Xorg but now I'm experimenting with Nvidia 7167 drivers using the Option "NvAgp" "1" in xorg.conf . I'm trying to make it freeze now. I heard disabling APIC works for some people but I havent tried that. Should I rebuild the kernel without support for local APIC on single proc.? i can

I am also still having problems setiing udev rules to allow correct permissions to the /dev/nvidia*

help me please!

For the rules check...
/etc/udev/rules.d/udev.rules
Check that you've this line: KERNEL="nvidia*", NAME="%k", GROUP="video"
If you've it, open /etc/group and be sure that you user is there, my line there looks like: video::18:root,gbonvehi

For the random crashes, i've been suffering them with the official nvidia drivers, I did a tail look at the log file from another machine and spotted a function called WAIT being called be the drivers causing a freeze, i'm right now testing the open-source ones ("nv") and been working ok. Once i'm sure it's a bug i'll post something to nvidia people.

In /etc/group my line said video:!:18:grant so I changed it to video::18:root,grant

I experience random crashes with both the "nv" and the "nvidia" drivers.
