Default 3xx drivers causing EQ overflow

So, I'm running gentoo linux for amd64, and recently (last week) upgraded to the 3xx driver.

I'd thought the problems I was having were with flash, so I removed adobe flash. But I still have the problems, any time I ran any sort of video playback. This is what shows up in my Xorg.log.0 file:

Code:

The screen would start flickering, and eventually freeze. The only way to recover would be to kill the X server.

Downgrading back to the 295 driver appears to have solved the problem. Any ideas what's going on with the driver?

Cheers,

Default Re: 3xx drivers causing EQ overflow

To help a bit in diagnosing, here's the output of nvidia-bug-report.sh. In particular, I draw attention to the following lines (which, iirc, occurred right around the days when X was freezing):

Code:
Jun 25 22:09:45 domo-kun kernel: NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt context
Jun 25 22:09:49 domo-kun kernel: NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt context
Jun 25 22:09:57 domo-kun kernel: NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt context
Jun 25 22:10:01 domo-kun kernel: NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt context
Jun 25 22:10:05 domo-kun kernel: NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt context
Jun 25 22:10:09 domo-kun kernel: NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt context
Jun 25 22:10:13 domo-kun kernel: NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt context
I'm afraid I don't have any concrete information on what's triggering the overflow, because it seems to happen at random.

Thanks again for the help.

Cheers,

EE

Default Re: 3xx drivers causing EQ overflow

Please provide information as much as you can get to reproduce the issue :
- Bug report file by running nvidia-bug-report.sh script as root.
- Reproduction steps in detail
- Desktop Environment you are using like KDE, GNOME, Unity etc…
- Window Manager you are using Compiz, gnome-shell, Kwin, Unity etc…
- Is the use is specific to GPU, System hardware, OS , Software Component etc…?
- Using any display manager like gdm, kdm etc…

Default Re: 3xx drivers causing EQ overflow

Hi! Thanks for the answer/questions. The responses are as follows:

1) bug report is attached to the post on 07-07-2012
2) reproduction steps … um, use the WM? This is a cumulative effect; I don't have any specific steps that seem to be causing it. It *may* be tied to using heavy 2D hardware acceleration (say, watching flash videos with VDPADU enabled), but that's purely speculation. The debug script may have more info on what's going on. I'm given to understand that there is a long-standing bug dealing with hardware acceleration, but I can't say if this is related.
3/4) I'm using FVWM, with a mix of KDE and GNOME apps installed.
5) Hardware is a BFG water-cooled GTX280. Temp never gets above 60°C. It is not related to using any specific device on my system. OS is Gentoo Linux, 64-bit kernel version 3.4.4. But there is nothing specific I'm doing that causes the problem.
6) DM is kdm

okay, first off, welcome back. I hope you guys have fewer problems with your forum.

I'm still having problems with EQ overflow, and it occurs now also with the 295-series driver. This is my current Xorg.log.0 file (at least at the end, where it was freezing):

kernel is now 3.5.0. I notice a higher liklihood of problems when running CPU-intensive processes in the background (say, compiling something) while running graphics-intensive programs in the foreground (in the most recent case, running LIbreOffice with a lot of graphics in the document).

Any suggestions what this might be? The 3xx-series driver doesn't last den minutes before the X server crashes out.

Cheers,

Default Re: 3xx drivers causing EQ overflow

PS, I should also note: this problem becomes *way* worse if I disable Hardware Acceleration on Adobe's flash plugin (yes, "disable." I have to set "EnableLinuxHWVideoDecode = 1" in /etc/adobe/mms.cfg to avoid crashing). However, even closing all my browser windows, killing any zombie processes, etc, after flash started freezing does not stop the system from being manifestly unstable.

Default Re: 3xx drivers causing EQ overflow

Recently I started getting that message too accompanied by 2 second hangs:

NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt context

I've backed up from 295.59 to 295.33 in an effort to fix this. I think it all started with an OpenSUSE kernel/x.org update though. (Driver 302 fails to rotate my screens so I couldn't try that.)

All I use is Thunderbird, Firefox, Konsole, Emacs ... not even a 3D wm, good old 2D because Xinerama + triple rotated screens won't do the fancy stuff. I have to reboot every day because the 2 second hang starts happening a lot after a while.

Default Re: 3xx drivers causing EQ overflow

After 3 days of using 304.32 drivers without any problems, I hoped that it will not lockup. But 5 minutes ago it happend. I could still access it with ssh, but I couldn't restart xserver (lightdm), it would always get killed immidiatly.

Here is the trace from the logs:

Default Re: 3xx drivers causing EQ overflow

I just found this thread and am having the same constant EQ overflow issues. My uptime is usually less than a day. It happens most frequently initially when I open firefox, everything but my mouse locks up with no resolve, I hear my cpu fan shoot way up and I have to do a hard power off. It's happened once with mplayer with vdpau.

-I use XFCE desktop with xfwm, no compositing.
-I'm on 3.10 kernel, Xorg server 1.14, Slackware 14.1
-Zotac GTS 450 AMP Edition with 331.20 drivers, problem remained with earlier 3xx drivers.

Xorg.log looks like this:
