Output from glxgears with RADEON_DEBUG=all
I just upgraded from 2.6.33 to 2.6.35-rc5, and whenever I try to run glxgears or any of the mesa demos only a black window is displayed. There is nothing interesting in my dmesg log. I am using the latest git versions of libdrm, mesa, xf86-video-ati, and X server 220.127.116.112. My card is a Radeon Xpress 200M IGP (RC410) I can give bisecting the kernel a try, but first I wanted to see if anyone had any ideas about what might be wrong. Previously, I was running a patched version of 2.6.33 to work around this bug: https://bugzilla.kernel.org/show_bug.cgi?id=15626 . The fix for this bug made it into one of the 2.6.35-rc* releases.
can you attach your dmesg?

drm/radeon/kms: add query for crtc hw id from crtc id to get info V2
Userspace need to know the hw crtc id (0, 1, 2, ...) from the drm
crtc id. Bump the minor version so userspace can enable conditionaly
features depend on this.
V2 use num_crtc and avoid DRM_ERROR

That patch fixes the problem.
This bug is not completely fixed contrary to what I reported earlier. 3D apps (e.g glxgears or any mesa demos) only work if I boot with pci=noacpi. Otherwise, without pci=noacpi I am still experiencing the same problem with 2.6.36-rc4 as I originally reported.
