I've been doing some more testing. With, and without, the commit_ring patches, even in pci mode, I can get X to hang without too much effort by firing up several glx demos and then x11perf. One of the glx programs will hang holding hw locks in r128WaitForFrameCompletion() from r128CopyBuffer(). The other glx programs are in the drmGetLock() ioctl from one of the r128render* functions, and x11perf in select from _XWaitForWritable().
Once the glx programs and x11perf are killed, the X server hang clears, but any attempt to start a glx program will hang the X server in the same r128WaitForFrameCompletion() from r128CopyBuffer() condition on it's first frame. A restart of X is required to reset drm.
