What version of the r200 3D driver? If you're using the one from the xlibmesa-dri package, please try a CVS snapshot, the current version of xlibmesa-gl1-dri-trunk at the very least. > The chip appears to hang with the following RBBM_STATUS: 0x80316100. > The CP_RB_[R|W]PTR registers also freeze. > > > The backtrace from X is as follows: > > > (gdb) bt > #0 0x4019da44 in ioctl () from /lib/tls/libc.so.6 > #1 0x084b6c7c in drmDMA (fd=5, request=0xbffff610) at xf86drm.c:796 > #2 0x082fe23b in RADEONCPGetBuffer (pScrn=0x8b5c518) at radeon_accel.c:490 [...] > It seems that this ioctl causes the kernel to simply execute the following > repeatedly: > - - radeon_cp_buffers > - radeon_cp_get_buffers > - radeon_freelist_get > > I guess the chip locks up somewhere prior to this, and the driver only notices > it when it runs out available buffers or something.

It might, as might enabling debugging output in the DRM and/or the 3D driver. Tracking down lockups tends to be very tedious and hard though, so let's just hope you aren't using a current driver. :\ -- Earthling Michel DÃnzer | Debian (powerpc), X and DRI developer Libre software enthusiast | http://svcs.affero.net/rm.php?r=daenzer ------------------------------------------------------- This SF.Net email is sponsored by OSTG.
