Running 2.8b, One of my GPU's after finding a share its hashrate drops to 0.0mh, it starts at >30mh then as soon as a share is submitted with that particular card it drops out.  I have two models of this card, same memory, both with stable overclock.  One runs fine with 2.8b, the other has the issue.  I have tried changing my -mi for that specific card lower and the problem persists.  Running previous PM versions the card runs fine.  Is there a way within the same prompt to individually designate which kernal a specific card runs on?  If so is there an example config for my bat?
