The only reason why I didn't send it back is this: when I killall -9 cgminer and then starting it from init.d it detects all 3 hashboards with 60 ASIC each. At the same time on a regular boot they are not detected. My concern is that it's software issue. cgminer 4.9 is currently preinstalled with a A3 firmware, but developer already released 4.10. Posted message yesterday on their support tread whether it's possible to install it on A3. If this not gonna work, I'll send it back.
