There are many more threads on this problem but no solutions. This is not an isolated problem, but I get the feeling NVIDIA doesn't realize the scope of the problem. If you've experienced this problem, please post relevant information so we can get NVIDIA to fix this problem once and for all.

My current relevant hardware:

ASUS A7V600 [VIA KT600] (Upgrading the BIOS didn't make a difference)
PNY GeForce4 Ti 4600

My current relevant software:

Slackware 9.1
GCC 3.2.3
Kernel 2.4.26 (Using 2.4.22, 2.4.23, or 2.4.24 didn't make a difference)
XFree86 4.3.0 (Using 4.4.0 or XOrg didn't make a difference)
NVIDIA-Linux-x86-1.0-6106 (Using 4496 or 4620 didn't make a difference)

Disabling AGP didn't make a difference.
Not enabling fast writes didn't make a difference.
Not enabling SBA didn't make a difference.
Not using framebuffer console didn't make a difference.
Disabling ACPI with acpi=off didn't make a difference.
Disabling APIC with noapic didn't make a difference.
Setting pci=noacpi didn't make a difference.
Setting pci=biosirq didn't make a difference.

It's definitely not a hardware problem. I don't get random segfaults, which would indicate a hardware problem. I can run Quake 3 and Unreal Tournament 2004 for several hours without problems, which wouldn't be possible with bad hardware. I've tested the memory with memtest86 and found no problems. The video card isn't sharing an IRQ with any other device.

The system doesn't really crash. X simply stops responding. The system continues to run in the background. This problem does not occur with the open source "nv" driver.

After dealing with this problem for several months, I finally figured out a pattern. The problem only seems to occur if I run X for several days, then restart it. The "lockup" then occurs within 24 hours or so. I don't know if this is the case with everyone else, but perhaps that might be a clue as to why it happens.

yeah, yeah, formerly also known as the pci_badness problem because a visit to crash city used to be accompanied by a line in the syslog saying "pci_badness". 6106 still shows the crash (for the people affected), but it doesn't leave a trace in the syslog anymore. The cause has never been found.

In my case, disabling AGP seems to have fixed it since I stopped loading the agpgart module. I'm going on 3 days straight now without this problem, All the other options mentioned by toastyx had no effect on it for me either. I'm running kernel 2.6.6, so it seems unlikely to be kernel-based in some way. I do know it would usually freeze if I ran X for several days, but I recall a few occasions where it happened much sooner and it didn't seem to require an X restart to occur. One possible clue: I have a Via KM400 chipset (very similar to the KT400 I understand), so maybe the problem is related to Via chipsets?

i've had the problem as well with no resolution to the problem.

i'm running without AGP atm, but i plan to fix that... someday, lol (i'm lazy). i also get frequent lockups, but commonly get the problem where X freezes and my mouse pointer still moves. i'm unable to operate anything else that the kernel is able to do (for example ctrl+alt+f1 and numlock).

i also changed video cards from my gf2 mx400 to a fx5900u modded to a 5950u, and i had the exact same problems. i previously had an ati 9800 pro aiw, and i seemingly never had these problems with it.

i will mention that 2 times i can think of (probably more), konqueror for KDE caused this type of crash, when clicking on a combo box. i could tell that they were related because of the way it behaved in each situation. a bit hard to explain in text, but basically i just feel it too ironic that i've had multiple crashes of this sort that happened somewhere between clicking the combo box and moving the cursor to the option (only to find out that it doesn't highlight, and i've gotten the nasty bug).

i will try to provide as much more information as possible later -- but for my system specs check my sig.

I get this problem also, both with the 5336 & the 6106 drivers. I do not get
the problem when I have a gf4 mx440 in the box, only when I have an fx5700 installed.

Ditto

See my previous post, with detailed system specs, etc:
http://www.nvnews.net/vbulletin/showthread.php?t=27645

The post was made before the 6106 drivers were released, and my 5700 is still
gathering dust on the bench, with no change to my situation other than the badness in pci
message going away with the driver update. The card model I have is a Leadtek
Winfast FX5700 A360 VIVO, and it unfortunately works flawlessly in xp.

Oddly, but perhaps specifically unrelated, two of the many times the system froze, my
mtab was corrupted.

Like wise 6106 still give lockups, I have now tried
NVidia agp
agpgart
no agp
recompliing with forced 2x agp
new power supply
new cooling system
a new motherboard
new processor
and if it had not cost so much I would try a new video card

Hi all,

Does anybody have tried to strace the X process when frozen?
I never had this problem (but many locks up, solved by disqbling AGP and having 384MB of ram instead of 512), but with some driver/kernel combination, X process eats all of my CPU and it was very slow. When I straced it, it was spending all its time calling gettimeofday (thousands of calls per sec).
Atm I'm running a 2.4.25 kernel with 1.0-4496 nvidia driver and it works pretty well.

I have the problem also, bump.

FX 5600, kt400, and i first saw it on a java app (azereus). Sorry for the lack of info, I'm tired.

Re: "screen frozen, but mouse pointer moves" bug
 
I have the problem too with the latest nvidia driver Version 1.0-6106.

I have a PNY Quadro4 200 NVS PCI adapter installed in a Tyan Thunder i7501 Pro
Dual Xeon Board. I'm using SuSE 9.1 Professional and I want to use Twinview. The
open-source driver nv works fine but it does not support twinview.

I did everything discribed in SuSE NVIDIA Installer.
If I use kdm and start an X-application my screen gets frozen a few seconds later.
Using gnome helps increasing the time until screen gets frozen.

The XF86-log file does not show any error.

I have really no idea what's going wrong.

I tried many options like

Option "NvAGP" "0"
Option "RenderAccel" "On"
Option "IgnoreDisplayDevices" "DFP,TV"
Option "NoRenderExtension" "Off"
Option "Accel" "Off"

but nothing worked.

I posted the output of nvidia-bug-report.log-file to linux-bugs@nvidia.com but until
now I didn't get any response.

Hi,

I have the problem also. I have a Asus P4S533 motherboard (SiS645DX chipset), and a Leadtek Winfast Ti4600, and kernel version 2.6.7.

strawks has given me an idea, I'll try running X under GDB (GNU Debugger), and see if this reveals anymore information. strace isn't detailed enough, it only logs calls from user space to the kernel.

I'll let you know how I get on.

Regards
elFarto
