Okay, I found the place in source that triggers this. It happens in the function r600_ib_test. The interesting thing is that not the ib-command itself is responsible but the fence that is emitted afterwards (proved by removing the fence command, where the problem went away). I don't know enough about the command semantics to make a guess what goes wrong there. But maybe you GPU folks have an idea?
