It's another chip, actually, but thanks for info. Mine is LSISAS3008:

     vendor     = 'LSI Logic / Symbios Logic'
     device     = 'MegaRAID SAS-3 3008 [Fury]'
     class      = mass storage
     subclass   = RAID

Looks like your problem with SMART may come from a very old firmware, my 
controller had same problem - disk was simply detaching after requesting 
SMART data. This was fixed in the recent firmware version. I suggest you 
should try the firmware upgrade.
