These are normal debugging messages and should only appear if the verbosity for the log file is set to level 4 or higher, e.g. using the -logverbose command line option to Xorg.

Does that still happen with current xf86-video-ati Git?

It's maybe the new gdm which start X with the -logverbose option (???), as I didn't set this option myself.

Oh... you are right, I had tested with the Xorg in [testing] but I hadn't thought to compile xf86-video-ati-git... and it seems to work, I can't reproduce the bug with the today's git.

Thanks for the tips, the problem seems to be solved !

Apparently I spoke too fast... gnome-shell has freezed today, just after I've unlocked gnome-screensaver. But i have nothing in dmesg or Xorg.log.

Anyway, it didn't seem to crash with games.

When this happens, can you get a gdb backtrace of gnome-shell and/or the X server process, and attach them here?

I suspect you were hitting two separate problems then, and that one was fixed in Git (probably the page flipping fixes).

I will try, but the problem seems very randomly, and difficult to reproduce.

Sorry for the delay, I haven't had time to work on this sooner.

The "freeze" seems to begin to (ramdomly) happen after that gnome-screensaver switches off the screen.

As Archlinux don't provides debug packages, I must recompile some packages, and I have an error when I try to recompile X, I'm trying to solve that.

But the gnome packager provides some debug packages for gnome, so I can have a backtrace when the problem occur.

I don't know if it's usefull, maybe I should open a bugreport on the gnome-shell bugzilla too ?

Posted some days ago.
 
Because it can be just a bug around the radeon driver in kernel I opened a new bug here.

Would be intersting to see if it freezes your system in the same way, if you visit the website I mentioned in my bug. So we can be sure, that is the same issue.

My system do not freeze when I visit http://piratpix.com/bpt2011.1/index.html and browse pictures with Epiphany, so I don't think it's the same issue.

Thanks! That is bad, or good.

Did you clicked on the thumbnails or just viewed the slideshow? Clicking on the thumbnails is causing the issue, the slideshow not.

Forgot something important!
Are you using the last official xf86-video-radeon driver or the one from git?

Yes, I have clicked on the thumbnails, and I use the git version of the driver.

May be this is related to https://bugzilla.gnome.org/show_bug.cgi?id=650857 ? (But Intel and NVidia owners are also affected)

Thanks for the link.

You are right, this problem seems very very close to mine.

I uninstalled gnome-shell-extensions-mediaplayer, and it seems
that it solves my problem.

Thanks to everybody, and sorry for the noise, it wasn't the fault of radeon driver or gnome-shell.

BTW, these are harmless debug messages which are suppressed by default. Somebody or something seems to have increased the X server's log level.
