Is it normal ops to dispatch an airplane after a stick shaker was on throughout the previous flight (Lion Air 610)?
Well, if the shaker was running abnormally like that, the crew would have done a QRH procedure, if any, for that condition, and reported the snag at the next stop, and something would have been done by maintenance to release the plane.  Like a part was changed, or the problem went away and couldn't be duplicated after a test was done on the ground, whatever was required to get a maintenance release.  It would have to have been released as serviceable, one way or another.
