Comment # 32 on bug 72785 from 
Doesn't work for me either with llvm 216281 and mesa git

Oh and maybe it's not known, at least it wasn't so clear to me: I earlier wrote
how my GPU wouldn't get as warm as I expected nor did it display the expected
hashrate. This seems to be entirely controlled by the --intensity parameter. An
intensity of 10 or 11 seems to work okay to not get too many H/W errors and
higher results.

But I let it run for about an hour and bfgminer didn't seem to create a single
usable result again.
