Hi,

After a recent world emerge, X11 seems to hang frequently and unrecoverably, due to Firefox. This seems to occur when I load a page with flash animations.

I have tried rebuilding xorg-server, firefox, and adobe-flash with no success.

This error message seems like it might be informative but I can't interpret it. I get one of these about ever 2 seconds during the hang. Any clues?

I've seen stuff like this on my Intel chipset graphics as well, but it's not as frequent (but it does recover), not sure what the issue is. However make sure you're running the latest driver including ~architecture, it may have fixed it.

I seem to have the latest xf86-video driver installed. Should I have libva-intel-driver too?

You are running the latest stable x11-drivers/xf86-video-intel. eccerr0r told you to try the latest testing x11-drivers/xf86-video-intel, which as of my last sync would be =x11-drivers/xf86-video-intel-2.99.911.

However, since that is a kernel message, I would focus on the kernel, not the user space driver.

Thanks for the advice. I'm somewhat reluctant to rebuild the kernel at the moment since I don't have a working grub installation:

But I'll investigate kernel issues a bit further.

Flashplayer cannot crash X11 without the presence of an X11 bug. The new flashplayer may not trigger the X11 bug that was affecting you before, but the bug is still there and could be triggered by some other program.

From dmesg I would say that this is not an X11 bug. Probably Flash tries to use OpenGL but encounters a kernel bug.

You can also work around this by not allowing Firefox/Flash to use 3D acceleration:
Code:
$ LIBGL_ALWAYS_SOFTWARE=1 firefox

I tried starting firefox with LIBGL_ALWAYS_SOFTWARE=1 firefox and it still seems cause X11 to freeze frequently (never recovers). Not 100% sure it is flash related but it does seem to happen when I hit websites with ads. Here is /var/log/messages from the freeze:
