Created attachment 73742 [details] patch When i looked up register 0x00008040 i saw that it was defined as WAIT_UNTIL. The function that prints that error is 'evergreen_cs_check_reg' in evergreen_cs.c. Since the WAIT_UNTIL is not present in reg_srcs/cayman (i have a radeon 6950) the cayman_reg_safe_bm test fail and since WAIT_UNTIL is not present in any of the switch cases it hits the default case. But WAIT_UNTIL was present in reg_srcs/evergreen, so i copied the WAIT_UNTIL line from evergreen to cayman. I also copied the rest of the WAIT_UNTIL_POLL* because they seemed related. This fixed the issue for me but i do not know if this is the proper fix. Tested on kernel 3.8.0-rc5 and wayland/weston master and mesa master.
