I believe this issue was fixed in kernel-2.6.33.2-57.fc13

Okay, last time I tried was with prehistoric 2.6.33.1-24-fc13.i686, so I upgraded my test installation to 2.6.33.2-57.fc13.i686 and kmod-nvidia-195.36.24-1.fc13.3 from rpmfusion following your advice.

The system runs for more than 8 hours now and things look good. I even played around with gnome-shell and did some screencasting. No matter what my Fedora is rock stable again. Funny enough I was trying every workaround suggestion and Voodoo magic I could find on the net for several month now and just between my last try and this bugreport the problem was fixed.

Thank you very much Leigh, would you just give some last assistance with closing this bugreport as I'm not familiar with this bugtracker and what tags are to be set?

Here's a link that explains the tags

https://bugzilla.redhat.com/page.cgi?id=fields.html#status

Thanks again Leigh, but even with the link you provided me I have no clue how to re-open this bug. Unfortunately the freezes hit me again. 

As I still have no idea how to reproduce the freezes on purpose I probably just was lucky when my system seemed to be stable. On the other hand there were some kernel updates lately and maybe the bug was reintroduced with one of those.

I installed F13 RC2 i686 yesterday and the freezes are back with 2.6.33.3-85.fc13.i686 and kmod-nvidia-195.36.24-1.fc13.4 from rpmfusion (dracut rebuild of initrd and blacklisted nouveau).

Disabling IRQ #16

2.6.33.4-95.fc13.i686 with "Nvidia Linux Display Driver 256.25 Beta" and the system also randomly freezes. 
Seems like there will be no fix or workaround from Nvidia's side anytime soon and all my hope lies on kernel developers now.

I did some investigation before and:
1. the issue started appearing since the last of 2.6.31 kernels in F12, and is present in F13
2. the problem seems to be fedora specific, ubuntu/debian unstable/arch do not have this problem
3. comparing the kernels configurations between 2.6.32 ubuntu (working) and 2.6.32 F13 (affected) the only options that drew my attention were: CONFIG_X86_X2APIC, CONFIG_INTR_REMAP, which might come in handy if you have a system with a large number of interrupt lines (not a typical desktop system)
4. somehow Gigabyte 965P-DS* main boards are present in most affected systems (judging by information gathered asking google) - maybe a hardware/firmware bug?

Still, due to lack of time, I have not built a custom kernel for with the options listed above set to disabled. Actually, it might be a reasonable next step to do.

Thank you Maciek! I wanted to build a custom kernel myself now following your hint and the guide at the Fedora wiki, but I fear I am by far not skilled enough to help tracking this bug down further:

http://fedoraproject.org/wiki/Docs/CustomKernel

Unfortunately I got stuck at "Configure Kernel Options", because I found neither CONFIG_X86_X2APIC nor CONFIG_INTR_REMAP in one of the config files. The files I looked for those options were:

~/rpmbuild/BUILD/kernel-2.6.33/linux-2.6.33.i686/config-*

~/rpmbuild/BUILD/kernel-2.6.33/linux-2.6.33.i686/configs/kernel-2.6.33.4-i686.config

config-2.6.32-21-386 from linux-image-2.6.32-21-386_2.6.32-21.32_i386.deb (Ubuntu)

Have you tried adding 

intel_iommu=igfx_off

or

iommu=soft 


to the end of kernel line in /boot/grub/grub.conf  ?

Sorry, I should have mentioned that. I tried intel_iommu=igfx_off after I found another bug, which I thought might somehow be related to my problem:
https://bugzilla.redhat.com/show_bug.cgi?id=538163

Before that I tried a lot of possible workarounds, mostly taken from some forum posts and without realy knowing what they are all about. Here is what I tried:

Added to kernel line in /boot/grub/grub.conf:

intel_iommu=igfx_off
iommu=soft
noapic
acpi=off
acpi=off notsc
pci=nommconf clocksource=hpet
notsc clocksource=hpet
notsc clocksource=acpi_pm

Added to device seciton in /etc/X11/xorg.conf:

"AccelMethod" "EXA"
"AccelMethod" "XAA"

I also set PowerMizer to high performance all the time as mentioned here:
http://www.nvnews.net/vbulletin/showthread.php?t=143434

Option  "Coolbits" "1"
Option  "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerLevel=0x3; PowerMizerDefault=0x3; PowerMizerDefaultAC=0x3"

Nothing changed my experience, after some time the system freezes, sometimes the screen even turns black. Then it either needs to be rebooted using SysRq+REISUB or (very rare) GDM comes up with a login screen again. I think GDM restarting is mostly when the freeze occurs before GDM has been completely started, but I am not sure and as being said, I can not reproduce the issue.

Also note that Xorg doesn't need to run at all for the freezes, I also faced them several times when trying to get a nvidia-bug-report.log from runlevel 3 (nvidia kernel module was loaded however).

The above options aren't useful for nvidia and should be deleted.

Remove the powermizer line as it shouldn't be there , I believe the powermizer line should be added in a conf file in /etc/modprobe.d/

This was just to sum up what I tried so far and probably most of those thing were just pretty stupid. However I always switch back to a clean Out-of-the-Box install whenever I messed things up with any workaround (I have a dd image at hand for that).

hope that someone solves the problem. For me are F12 and F13 unusable.

Happens to me as well. Interestingly the Bug only appeared after I switched my Mainboard because it doesn't work anymore. Both with Fedora 13 and NVIDIA Geforce 8800 GT. I couldn't create a kernel log so far, because of the crash (it freezes after a few minutes or whenever I start an OpenGL program like glxgears or nvidia-settings (after a few seconds).


Before I had a MSI P35 Neo2-FR/FIR (Intel P35 chipset)
I now have a Gigabyte GA-EP45T-UD3LR (Intel P45)

Maybe it's related to the chipset driver? (Just a guess).

If this problem associate with chipset, then my chipset - Intel P43

In my system the chipset is intel X48. It´s a Sun Ultra 24.

I switched from the Gigabyte 965P-DS4 to a MSI P43T-C51 and it is still the same. As soon as the proprietary Nvidia driver comes into play it is just a matter of time and the system freezes.

I am sorry for excluding other chipsets in the first place, I thougt only P965-Boards are affected. Note that I could not find the "irq 16: nobody cared" line in /var/log/messages when the freeze occured on the MSI-Board. Please have a look at "logs-GTX280-MSI-P43T-C51.tar.gz" for reference.

I'm a bit afraid we wont get any help from either the Fedora or NVidia people on this issue so I suggest we pool our resources and try to figure this out by our selves.  After all, we do have the source of the kernel it self.

We know this is a Fedora only issue and only in F12 and F13 and apparently it hits only Intel based chipsets.  So I installed the F13 kernel srpm and took a look.

Since this is a Fedora only issue, one of those 141 patches has to be to blame.
I'm going to start rebuilding kernels and try to isolate which of the patches is to blame.

Does anyone have any ideas on what could be a good place to start?
Prehaps these?

I think pretty sure I'm suffering from this bug too.
- The problems started for me after the upgrade to Fedora 12.
- Fedora 11 was rock stable.
- Fedora 13 still has the issue.
- First, I thought it was nvidia driver related. Then I removed all nvidia stuff, and I'm using nouveau now, but the bug still is there.
- Sometimes, my system runs for hours without a crash.
- Sometimes, it hangs already during boot.
- The more hardware is connected, the sooner the crash occurs (e.g. external disk, OpenMoko phone, both via USB).
- I have the impression that I have less frequent freezes after using MSI interrupts for my audio (and nvidia, when I was still using this driver).
- See this bug, which actually is about the same issue: bug #588036, I refer there to some other bugs and reports that look related.
- I'm using an ASUS P5B-MX motherboard.
- Sometimes the system freezes without leaving any logging about errors.
- Sometimes there are errors logged.
- Let me know if logs during the crashes are useful, I can attach them to this bug.

Thanks for all your efforts Richard. I tried 2.6.33.5-124.fc13.i686 together with kmod-nvidia 195.36.24 from rpmfusion lately and nothing changed. Then I installed Ubuntu 10.4 and used it for several days. Now as the freezes occur randomly I am not absolutely sure, but as far as I could see Ubuntu is not affected, so I would like to confirm this again..

Unfortunately all I can contribute is trying most recent Fedora kernels and reporting back, although I fear that is not very helpful at all.

I'm using the latest kernel-2.6.34.1 from koji and the latest official nvidia 256.35 drivers and the system seems to be stable for the last two days

http://koji.fedoraproject.org/koji/buildinfo?buildID=182791

It's great to hear some good news.  It takes me just under 2 hours just to compile my PAE kernel.  NVidia 256.35?

rpmfusion only has 195.36.  Does NVidia ship something much newer than rpmfusion does?

I find it on http://atrpms.net/dist/f13/ , but no time for test.

This morning I removed (rpm -e) all rpmfusion nvidia software from my machine and downloaded the 256.35 install kit directly from NVidia's website since rpmfusion still has no 256.35 rpm's.

[root@morticia ~]# uptime

Not a single crash today :)    I know I meight be a bit premature but it's been ages since I made it past 10 minutes uptime :)

Spoke too soon.   With the 256.35 drivers, the situation is much better.
Did get a crash:

It might be a workaround to enabled 'PEG force x1' in your BIOS.

I experienced random crashes both with nvidia and nouveau drivers. Currently, I'm using nouveau, and since I enabled this BIOS setting I did not have a single crash for nearly two months. Maybe it works for the nvidia driver as well.

See also bug #588036.

Hi folks, 

This is by no means a Fedora-only issue. I run Ubuntu, and after a motherboard (+cpu) switch, this started happening to me too. Maybe I can provide some info, as I'd very much like this issue to be resolved.

I had no issues at all on the old motherboard:
- Old MB: Asus P5W DH Deluxe (Intel 975x chip-set) + Core 2 Duo E6600 CPU

On new motherboard I get the behavior described in this bug.
- New MB: Asus P6T SE (Intel X58 chip-set) + Core i7 930 CPU

Same Ubuntu installation in both cases.
- Kernel: 2.6.31-20
- nVidia driver: 185.18.36

Problem did not go away after upgrading nVidia driver to 256.53.

The log messages "NVRM: os_pci_init_handle: invalid context!" is printed from the nVidia driver kernel interface code in kernel/os-interface.c (in the unpacked nvidia driver directory).
This is an error condition - when the os_pci_init_handle() function is called in an interrupt context, from the looks of it.

That's as far as I've come.
And it seems like running glxgears is a good way to force the bug to manifest.

Cheers!

Addition: enabling "Sync to VBlank" in nvidia-settings OpenGL Settings seems to have removed the problem. Running Starcraft II in a window (in Wine), glxgears, and playing a video simultaneously now for 30 minutes, plus playing QuakeLive, with nothing in the syslog and no problems.

We don't provide or support the nvidia driver.
