Default NVidia driver/connection problems

Hello.

I have an NVidia 6600 on FreeBSD 5.4-RELEASE, Xorg 6.9 and nvidia-driver 1.0.8178 and I am having ocassional problems when running some OpenGL problems.

Sometimes in the middle of the execution the system freezes for a while (about 30 seconds) and then the application crashes (not always, sometimes it continues normally) with messages like this:

Received signal 11, exiting...
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 135 (XFree86-VidModeExtension)
Minor opcode of failed request: 10 (XF86VidModeSwitchToMode)
Value in failed request: 0x1200002
Serial number of failed request: 35768
Current serial number in output stream: 35771

And the NVidia kernel module outputs errors like the following:

NVRM: Xid: 8, Channel 00000002
NVRM: Xid: 27, L1 -> L0

The card was previously without the AGP slot lock set, and was outputting a lot of errors (because it was randomly being disconnected and reconnected by the vibration of the cooler I think), but now the lock is on and this is the only error I notice.

The errors when the AGP lock was off were like the previous one (but much more):

NVRM: Xid: 8, Channel 00000002
NVRM: Xid: 27, L1 -> L0
NVRM: Xid: 8, Channel 00000002
NVRM: Xid: 27, L1 -> L0
pid 99360 (conftest), uid 0: exited on signal 12 (core dumped)
pid 19323 (conftest), uid 0: exited on signal 11 (core dumped)
pid 57511 (conftest), uid 0: exited on signal 12 (core dumped)
pid 68673 (conftest), uid 0: exited on signal 11 (core dumped)
nvidia0: detached
nvidia0: <GeForce 6600> mem 0xcd000000-0xcdffffff,0xb0000000-0xbfffffff,0xce000000-0xceffffff irq 16 at device 0.0 on pci1
NVRM: Xid: 8, Channel 00000002
NVRM: Xid: 27, L1 -> L0

Here you can see it was disconnected for a moment.

Do you think these errors are still about connection problems? What can I do?

If more information is needed just ask.

Thanks and Best Regards,
Ale

Does lowering the AGP rate help?

I am kind of a newbie to FBSD, how do I lower the AGP Rate? How do I get an AGP Rate? My Bus Type says PCI, am I doing something wrong?

zander:
Thank you for your reply.

I have tried lowering it to 4x, but the problem persists. It only happens with the same OpenGL application: a Quake II engine modification called QuDos.

The screen/system freezes for about 20 seconds, and then the kernel module outputs this:
NVRM: Xid: 8, Channel 00000002
NVRM: Xid: 27, L1 -> L0

The application crashes with the following message:
Received signal 11, exiting...
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 135 (XFree86-VidModeExtension)
Minor opcode of failed request: 10 (XF86VidModeSwitchToMode)
Value in failed request: 0x1400002
Serial number of failed request: 855
Current serial number in output stream: 858

What do you think about this?

bentman78:
You can view it with the sysctl command:

% sysctl hw.nvidia.agp.card.rates
hw.nvidia.agp.card.rates: 8x 4x

But you have to change it from the BIOS (you can also view it from here).

@alepulver: the vidmode extension problem doesn't look like it's caused by the NVIDIA driver; are you loading the extmod module? As to the Xid problem, does disabling AGP alltogether help? Also, which AGP GART driver are you using?

Default Re: NVidia driver/connection problems

I am loading the "extmod" module (omitting the "DGA" extension).

I have disabled AGP in the BIOS, but the problem persists (I changed "Primary Graphics Adapter" from AGP to PCI),

I am using the NVidia's AGP GART driver (I am not loading agp.ko and I have no NvAGP option in xorg.conf).

Are you sure these two problems are not related, because they always happen at the same time and under the same circumstances?

Sorry for the bad description I did before. Here is a clarification:

The system freezes about 20 seconds when I get that NVRM message, during that time if I try to switch to a terminal it makes the executable crash, otherwise it continues normally.
