I have a Thinkpad T20 with a Savage/IX-MV graphics chip. OpenGL applications crash with a SIGKILL (and a "VM: killing process <foo>" in the kernel log) if using vertex DMA. I traced down the bug: it seems to affect all AGP DMA transfers for savages, as it results from dev->agp_buffer_map being forgot to be set. Patch will be attached
Created attachment 7430 [details] [review] Fixes the reported bug
Sorry, wrong setting of the version field. The patch is against DRI CVS, not Xorg CVS which does not contain DRMs at all, if I did not miss it in WebCVS.
Thanks for tracking this down. The drm is actually in git now (http://gitweb.freedesktop.org/?p=mesa/drm.git;a=summary), but the patch should still apply easily. I'll test and apply this to drm git later today.
pushed to drm git.
