When rotating the 3D viewport with the middle mouse button in Blender, X seems to freeze. The screen doesn't update and X does not respond to input, except that I can move the mouse around. The system itself does not crash as I can log in using SSH. When I do, Xorg is still running and hogging the CPU. I'm using a vanilla debian linux kernel, 2.6.18, Xorg 1.2.0 and an ATI Radeon 9100. I have reproduced the bug with mesa and dri from git today.

I had a look at bug 8299 and bug 5376, but I don't think it's the same issue as I get a lock both with SWCursor enabled and MergedFB disabled.
Bug is still present in version 6.5.3~rc3-1 (Debian).
No change with 7.1~rc3-1.
What hardware/driver are you on?
An ATI Radeon 9100, using version 6.9.0 of xf86-video-ati. Xorg 1.4.99.905, Mesa 7.1~rc3-1 on linux 2.6.25.7.
I no longer own this hardware and have no way of reproducing the bug so it's probably a good idea to close this report.
