dmesg + stacktrace

Hi everyone,


Just in case, I wonder if there is not some kind of connection to this post: https://bugs.freedesktop.org/show_bug.cgi?id=92213
Also, I am not sure of the version of nouveau, so I give the information I know for sure there:
I am running Archlinux (Linux 4.2.2), KDE (5.4.4), Qt (5.5.0) on a x86_64 system. mesa is version 11.0.2 and xf86-video-nouveau is version 1.0.11-3.

Also, there is my lspci -vv:

And I have errors when running the system for too long.
There, you can access the stacktrace (on an Archlinux system). You also have the dmesg messages. There is a sample of what is displayed:

... and there is more there. Please see the attachment.

I can also add that it makes the plasmashell application hangs for a while, with 100%CPU usage. After some time, the system is responsive again, with some glitches in the interface (meaning, some icons disappearing or wrongly displayed for instance. Once, it made the file explorer dolphin crash). I have been told that it could be related to a Vsync problem.

It has been identified by a problem with nouveau (I refer you to the comment 4 of the ticket, that gives better understanding of the problem):
https://bugs.kde.org/show_bug.cgi?id=353292#c4

Thank you for your time! And keep the good work going!
Cheers.

Hi Ilia Mirkin,

The symptoms seems to be the sames, but are you sure it is the same bug? I mean, it could happen when I resume my session, but I don't know if it does, and the problem I report there is not related to the problem of resume. It is just a plain raw crash when I use it, and it starts working again after few minutes.

And I am sorry, but my knowledge in GPU is too small to understand the thread of the other bug.

Cheers

These errors should be fixed by the patch from the other bug (now in Linus's tree btw, should be part of 4.3-rc7). The rest is most likely fallout from those errors. If the issue persists with my patch, feel free to reopen.
