Using a HD 4670 still possible?

Using a HD 4670 still possible?

Hi list,

I'm currently trying to get a HD 4670 aka RV730 XT to work against X.org
1.16, xf86-video-ati 7.4.0 on a Linux 3.16.1.

Can anyone tell me: Should this card be able to handle an average Gnome
desktop?

The problem was: 3D rendering did not work at all.

Starting gdm lead to hanging Xorg. Calling glxgears on a twm session just
rendered a black window, which stayed even if the process was killed by
CTRL+C. I managed to get glxgears do do its job by setting "vblank_mode=0".

I guessed my card does not like to play along with vsync at all. So I went
ahead to disable vsyncing (tearing is still better than no display at all).
Setting it globally in /etc/drirc seems to get glxgears running.

Testing Xonotic on twm showed, that the card was now able to handle 3D.
But: gdm still was extremely sluggish and eventually froze. Starting
gnome-shell directly from startx gets me to the desktop, but any action
freezes the process.

Is there still hope for this card or should I get rid of it?

Best wishes,
Christoph

Of course.

It sounds like there's a problem with interrupt processing on your 
system. Please provide the dmesg output. You might try 
disabling/enabling MSI to see if that works around the problem.

Thank you so much for this hint! Booting using radeon.msi=0 finally brings
the system into a usable state. The dmesg of a default boot (i.e.
radeon.msi=-1) is available at http://pastebin.com/gS1xHYPc

Can you file a bug report at 
https://bugs.freedesktop.org/enter_bug.cgi?product=DRI component 
"DRM/Radeon" and attach the dmesg output there?

Also mention what chipset your system uses and whether the card is AGP or not.
