Can you post a bit more, like some lines higher and a bit lower, it may be just resetting it from 3.0 to 1.5. Or it could be failing, just backup your data and maybe run some smart or low level tests, see UBCD.

It doesn't look like it's failing, to be sure I'd run a long test 'smartctl -t long /dev/sda' and wait for it to finish, then check if it completed.
