From: Noam Camus <[email protected]> This counter represents threshold for consecutive stall that which trigger HW threads scheduling. When this feature is enabled low values of this counter cause downgrade in performance and in the worst case even a livelock.
Remove those couple of lines and resort to HW reset value i.e. this feature is disabled (.sten field equals 0).
