 With the latest GATOS CVS - the one with changes from Peter Surda at the
 files radeon_driver.c, radeon_reg.h, fi1236.c, fi1236.h, msp3430.c,
 r128_dri.c, theatre.h and theatre_reg.h - the problem (apparently) is the
 same one that at first: corruption at login screen (xdm, kdm), the messages
 [drm:r128_cce_indirect] in the kernel log, and X crashes.

Patched in the wrong place, please try again.

Vladimir Dergachev


 With only the patch from Peter Surda to the file r128_dri.c no corruption at
 login screen, no messages in the kernel log but X crash with both mplayer and
 glxgears running, or only with mplayer after a while playing a video.

 BTW, which is the appropriate mailing list to discuss this stuff? I think
 that we're CC: to too many places... At this step we'll finish CC: to the
 linux kernel mailing list :)

   After digging around the code a bit, my current theory is that the

   where it releases the indirect buffer. Can you try if that fixes the
   problem?
 
  Yes this seems to have fixed it, here's the patch:
