Thanks for testing the recent build of smartmontools. Which RST driver version do you use?
There were actually a few reports that CSMI pass-through apparently does no longer work with some recent RST (11.*) or RSTe (3.*) drivers. The SSD optimizer and SMART display from Intel SSD Toolbox may also not work (http://communities.intel.com/message/158199)
HWiNFO support suggests to update to RST 22.214.171.1243 or RSTe 3.2 (http://www.hwinfo.com/forum/Thread-IMPORTANT-Known-Issues--412).
If possible, please test one of this new drivers with smartmontools.
