Too early :(

The dri cvs snapshot works fine on both it's own kernel module, and
the one that comes
with 2.6.8.1. So now what? (And does this mean it isn't a kernel bug?)

I have compiled both the kernel module and the replacement X server from the yesterday's CVS checkout of DRI (but according to "outdated" instructions in the Wiki). It made a difference against XFree86 4.4.0 + in-kernel radeon.ko.

The difference is that, instead of just hanging, after several minutes of run time applications (e.g. "really slick screensavers") print:

drmRadeonIrqWait: -16

and exit with status 1.

After that, 2D works, but the _next_ fullscreen OpenGL application hangs the system immediately on start.
