Radeon 9550 + xf86-video-ati = Crash

[Exershio]

I just installed the open source drivers (tried from the pacman repo (using Arch Linux) and the one from the GIT repo) and it runs really nice, almost as good as the FGLRX driver (which is a HUGE improvement since I last tried it last year). However, whenever I run a 3d application, after a little while (lighter programs like StepMania take a few minutes, fully 3d intensive programs is within 20 seconds or so), my entire desktop hangs to the point I can't move the mouse or input anything with the keyboard and I am forced to shut down the computer via the power button.

Sometimes the screen goes black and the monitor loses signal, sometimes it leaves the display frozen on the screen. Either way, I can't use my mouse/keyboard and everything just halts.

Any ideas? This doesn't happen with the FGLRX drivers or in Windows XP. I don't really want to use the FGLRX drivers, I'm pretty satisfied with the open source one (besides this problem, obviously). Any help would be greatly appreciated. :)

Btw, I'm using a Radeon 9550 AGP 8x 256mb (running it as 4x in the xorg config file since my mobo doesnt support any higher than 4x)

This sounds very much same problem that I run into using Ubuntu.

Solution was updating video-ati, mesa (7.4 branch) and drm (including kernel modules) to the latest git version.

More details are in bug report (https://bugs.launchpad.net/bugs/348450)

I installed libdrm-git and libmesa-git from ArchLinux's AUR, and it dropped my frame rate to unplayable levels.

My glxgears was about 1700fps before I installed the GIT libdrm/libgl and now it's 150fps. I had this problem before I installed the GIT versions, but I fixed it before by commenting out load "dri2" in the Module section. Now that I installed the GIT libdrm/libgl my FPS sucks again, only thing is, I still have load "dri2" commented out.

You can usually remove the complete Module section for recent Xorg releases. It would even start without xorg.conf.

Are you sure you are even getting hw rendering? Run glxinfo and check the renderer string.

[Exershio]

Yeah it's not doing HW rendering anymore I don't think:
OpenGL vendor string: Mesa Project
OpenGL renderer string: Software Rasterizer
OpenGL version string: 2.1 Mesa 7.6-devel

It didn't say that before I upgraded
