Kernel-2.6.31.6-134 seems to have a bug on R600 DRM

[Rudolf Kastl]

interestingly i just updated a radeon hd4650 box to latest rawhide and
the same error pops up again:

[drm:r600_cs_packet_next_reloc_mm] *ERROR* No packet3 for relocation
for packet at 45.
[drm:r600_packet3_check] *ERROR* bad SET_CONTEXT_REG 0x28014
[drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

kind regards,
Rudolf Kastl
