I thought I'd append a bit more and specifically the reason why it87
could not be loaded. In lm-sensors configuration for Wheezy, it said to
put two modules into /etc/modules: coretemp and it87. When lm-sensors
run under my current hardware with Jessie, it only says to add the
coretemp module. When I comment the it87, I no longer the the FAILURE
message during boot. 

My # sensors command no longer provides fan speeds and ALARM, which I'll
have to investigate some other time, but it seems it87 module not
relevant to this.
