I tried on my amd64 machine at home and got no panic, but strange
results instead.

root@petaure [~]# envstat
                  Current  CritMax  WarnMax  WarnMin  CritMin Unit

  CPU1 Sensor1:    50.250                                     degC
root@petaure [~]# envstat -c envsys.conf
root@petaure [~]# envstat

root@petaure [~]# envstat -S
root@petaure [~]# envstat

  CPU1 Sensor1:    49.250          -273.117                   degC

The -273.117 values looks ... wrong.
