how did you manage to disabled crossfire? this is the well known and often discussed HD5970 (cypress) crossfirex ATI driver problem. i have exactly the same error on my card and there is currently no way to workaround this problem except using -d 1. but this limits the usage to first gpu (well i think it is the "virtual" crossfirex'd gpu) but that also means we can not gain the full 5970 performance. but it should solve the random output of cracked hashes. we have to wait for ATI updating their drivers. till that, use -d 1 and dont forget -n 80 for max. performance
