It doesn't seem http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=a41ceb1c17af06a17c0d88e987215ef20b93c471 fixed it. Installed http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.36-rc6-maverick/. I think that's the first .36 release candidate with the patch in it, but I am not sure I am connecting the patch to the mainline release it got merged into correctly. But I previously posted about still having the problem with a more recent kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.36-maverick/. What should I do?

$ glxgears

Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
302 frames in 5.0 seconds = 60.378 FPS

Instantly after resizing:

drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See dmesg for more info.
