Description Marc B. 2011-02-13 12:29:13 UTC 
I don't know if I suffer a regression of nouveau in 2.6.38-rc4.

It feels like the screens tends to freeze often in that version but I cannot be
sure if it is the 2.6.38-rc4 release or something else.

The current 2.6.37 kernel has this in Xorg.0.log:

the similar behavior?

I have the slight assumption that the problem is more often triggered with the VirtualBox kernel modules loaded. I know that you guys consider this setup 'Tainted', however, it's a real-world setup that used to work.

This was not true. The beavior persists with -rc7. Screen will freeze _always_ after about 3 - 4 minutes with mesa-HEAD and xorg 1.10.0. 2.6.37 is fine.

This, however, seems to be something different. When I reported the bug there were no such logs. Maybe they just didn't get into kern.log or there are two bugs.

If you need more info on something, please ask.

If this problem occurs on a NVA8 it's not an regression. NVA3+ have some random lockups where nobody figured out why. So it never worked okay, although some changes in the codebase could have made it more likely to trigger the lockup.

I strongly suspect the PGRAPH_TRAP is a unrelated bug, since we never saw anything in the logs after random lockup.
Comment 9 Marc B. 2011-03-06 11:42:29 UTC 
I updated the whole X11 stuff to current git and the problem seems to be gone.

I have the freezing kernel running for about 15 minutes now and tried anything to make it freeze (composite WM, Firefox, several glxgears instances and fullscreen terminals just doing some stuff to make it print a lot of text (like cat'ing dmesg in loops)). Weird.

... but the workaround cannot be to upgrade X11 to HEAD. :)

Any hints on what one could do to track this down?
Comment 10 Marc B. 2011-03-06 12:01:33 UTC 
OK, consider this as 'not said'. Just a second after I hit 'Commit' to send the post the desktop froze. :/
Comment 11 Lucas Stach 2011-03-06 13:02:58 UTC 
Do you see this freeze on NVA8 only or also on other cards?

If it is only NVA8 there is nothing you can do, as nobody knows how to tackle this bug. You may pary that Ben finds a way to reprodue so he can hopefully fix this.
Comment 12 Marc B. 2011-03-08 08:42:13 UTC 
I have no other card to test over here. :/

rc8 still fails to behave like 2.6.37. Is this really going to be rolled out?
Comment 13 Lucas Stach 2011-03-08 11:26:25 UTC 
This _is_ already rolled out, as no nouveau version so far didn't lock up randomly on NVA8. It seems you were enormously lucky to not see them on .37.
Comment 14 Marc B. 2011-03-08 12:46:01 UTC 
To be honest, I doubt _this_ is rolled out. The behavior might be there in 2.6.37 but in 2.6.38 it seems to be worse. With 2.6.37 I have some random lock-ups leading to the GPU once in a month (I consider this normal, even as NVidia itself has problems like this with their drivers). The recent 2.6.38-rc kernels freeze actually after some minutes. And this can be reproduced.

But OK, since you seem to say that there's nothing we could do about it at this point - as nobody seems to know a solution - what do we do with the bug report? Close it? Sad to hear I won't be able to use the 2.6.38 release.
Comment 15 Florian Mickler 2011-03-08 15:36:50 UTC 
If you find the commit that made this worse it may hint at a solution or maybe just reverting fixes things... so if you can use git bisect (man git-bisect), please do so.
Comment 16 Lucas Stach 2011-03-08 15:40:44 UTC 
No please leave it open for now, just remove the regression flag. Also you could add _full_ dmesg output and the versions of your userspace (xf86-video-nouveau, x-server, libdrm and if installed mesa).

Dmesg after crash may also be interesting (hopefully we find something this time, but I doubt it).
Comment 17 Marc B. 2011-03-08 20:38:46 UTC 
Removed from 'regressions' due to request and perhaps actual sense.
Comment 18 Marc B. 2011-03-08 20:47:36 UTC 
Curently I'd already like to offer money for this to get fixed. Damn thing this seems to be so tricky... :/
Comment 19 Marc B. 2011-04-05 20:00:14 UTC 
nouveau.noaccel=1 'fixes' the issue. I have an uptime of 4 days now with 2.6.38.2 without any problem. But performance wise .... uhm.
Comment 20 Alan 2012-08-15 22:15:55 UTC 
If this bug is still seen with 3.2/3.4+ kernels please re-open
