I've just built mupen64 plus emulator and it crashed after a few seconds (after
emulator intro screen).

When running it, i get something like this :

Core: R4300: starting 64-bit dynamic recompiler at: 0xbc0200
radeon: The kernel rejected CS, see dmesg for more information.

inspecting dmesg gives this output:

[ 4250.120602] [drm:r100_cs_packet_next_reloc] *ERROR* No packet3 for
relocation for packet at 1140.

[ 4250.120625] [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !


the same behavior is on current mesa git.

hardware is RV515 (x1300 pro) on 64bit system. 

i'd like to know if that's a program issue, or mesa bug?
