Problem with Simulink 2015b (but not earlier) and Arduino Uno

I'm running class with a hardware component on Arduino. For years, we've been using the same models and everything has worked. However, some students recently came to me after running into an error:
No free Timer is available on the target to generate the base rate interrupt which executes the model on the target. All timers are used by Servo and PWM blocks in the model.
The only consistency seems to be that they're running Matlab 2015b (earlier versions don't seem to give this error). As far as I can tell, they are properly setting the device, and some other simpler models continue to work. They did inform me that when installing the Hardware Support Package, they now only have 2 options (Matlab, Simulink) instead of 3 (Matlab for Uno and Due, Simulink for Uno, Simulink for Due).
Does anyone know if Arduino Support in 2015b has broken Uno support in some way? Maybe by merging the Uno/Due package?

On your Simulink model, open Configuration Parameters window, select Solver. Click on additional options and uncheck 'Treat each discrete rate as a separate task'. That worked for me.

I do have the same problem. Have you found any solution? Ulrich
