I'd say to try 10.11 or maybe even go back to 10.10. I just installed some new GPU's last week and had similar problems. Ended up going back to older drivers.

+1 to what Harley said.
I had been running 10.10 stably for a while. I even had the 2x5970 system (4 GPUs) humming along nicely on DNETC up until this recent fiasco. Try 10.10, or bump up and see how 11.2 treats you...
I think I read something about DNETC handing out longer WUs now. Might run a few more and see if you get better results out of other WUs. That 5850 is taking 15:45 average. Good luck.
