Wondering if this is a known issue, or if anyone has suggestions to

Running FreeBSD 6.2-RELEASE-p4 SMP i386.

I installed nvidia-driver-100.14.11 from ports (Sep. 5 snapshot),
Linux compatibility enabled. After loading modules 'linux' and
'nvidia', I do:

# X -configure
# X -config /root/xorg.conf.new

At this point the system spontaneously reboots. 'X -configure' runs
fine and produces a configuration without issue, but the reboot
occcurs when launching X. Nothing is output to screen (it flickers as
if starting X), and nothing is written to /var/log/Xorg.0.log. I do
get the same behavior if running 'xorgcfg'.

Card info:

"NV41 [Quadro FX 3450/4000 SDI] rev 162"

nvidia0@pci7:0:0: class=0x030000 card=0x029b10de chip=0x00cd10de
rev=0xa2 hdr=0x00
vendor = 'NVIDIA Corporation'
class = display
subclass = VGA

I've tried an alternate version of the binary driver
(nvidia-driver-96xx) to see if there was any change, and it also
reboots on X startup.

Check your AGP settings and consult the readme, chapter 9, for the
latest driver. You should be running the latest driver with your card.

Make sure you have the correct AGP settings, either letting FreeBSD do
it in the kernel or disable the kernel and let the Nvidia driver manage
it.

So, I'm not having terrific luck with any combination of settings I try.

The latest FreeBSD driver release from Nvidia is the same as the
version in the ports tree. This is what I've installed.

Attempting the AGPGART route (building the driver with
"WITH_FREEBSD_AGP=yes" and disabling NvAgp support in xorg.conf) still
results in a reboot.

Going the NvAGP route (Building without support for AGPGART, setting
NvAgp to 1 in the xorg.conf, and setting hint.agp.0.disabled=1 in
/boot/device.hints) also results in a reboot when X starts. One thing
I notice here; when I specify hint.agp.0.disabled=1, and check the
output of 'kldstat -v' after booting, I still see several agp drivers
loaded:

$ kldstat -v |grep -i agp
387 pci/agp_ali
388 pci/agp_amd
389 pci/agp_amd64
390 pci/agp_ati
391 pci/agp_i810
392 pci/agp_intel
393 pci/agp_nvidia
394 pci/agp_sis
395 pci/agp_via

Is this a problem?

I suspect a couple of problems with what I'm doing. Number one,
there's several knobs to turn (in the driver, in the OS, etc.) and
it's possible I'm not getting the correct combination. Other thing is,
I've been told by a technician that this is a PCI Express video card,
so would AGP even come into play?

Probably not. I'm seeing the same thing on one machine, no AGP on MB, and agp
kernel modules loaded, but nvidia-driver doesn't care about it.
Let's kill all red herrings:
- Is COMPAT5X in the kernel?
- Does running `nvidia-xconfig --query-gpu-info' reboot the system?
- If you do not load the nvidia kernel module, but use Xorg's "nv" driver does
this reboot the system?

Determine cause of reboot:
echo dumpdev="AUTO" >>/etc/rc.conf
/etc/rc.d/dumpon start

Now, if it reboots again and no core is found, the kernel didn't crash but an
error occured in the hardware layer at which point I'd hit nvidia forums.

If there's a coredump:

and file PR.
