Public bug reported:
Using Ubuntu 16.04, Kernel 4.4.0-57-generic wrong temperatures also make
it into syslog:
Jan 2 20:22:27 server smartd[876]: Device: /dev/sda [SAT], SMART Usage
Attribute: 194 Temperature_Celsius changed from 110 to 112
Jan 2 20:22:27 server smartd[876]: Device: /dev/sdb [SAT], SMART Usage
Attribute: 194 Temperature_Celsius changed from 111 to 113
Not only is that wrong, it also tells admins that there was need to take
action. Eventually, it makes it into some monitoring tool, which thereby
abstracts the RAW_VALUE even further.
Note that in reality my drives have <40°C, just by reading SMART's
RAW_VALUE (and touching the drive with my finger).
Also note that the device model is "In smartctl database", according to
smartctl's output. That said, I'd expect smartctl to somehow "know" all
variables of my drive, including their meaning.
