Public bug reported: This issue is present in gallium drivers from mesa 7.10.x which are in Ubuntu 11.04. Ubuntu 11.10 is not affected, but the fix should be brought in to Ubuntu 11.04.
I have an ATI Radeon 3850. Using the default drivers (xf86-video-ati and gallium for dri), I get lockups within a few seconds of any operation using DRI (compositing, OpenGL, whatever). The issue is fixed in the meas commit ecc051d65b6e17115439fb3609cccfd59f6272bf on master and should be brought in to Ubuntu to address this lockup.
