Noticed that TRH.42m Ifan was at 0, indicating that it finally went over 80mA last night.  However, when I tried to connect (either rs or minicom), it didn't respond, nor to eio cycles.  Tried rebooting the box and it never came up.  Walked to the DSM and had no response on the console.  Finally power cycled the DSM and everything came back up, including TRH.42m with Ifan now 63mA.

As mentioned before, we'll keep watching this sensor.

It was annoying to have tower DSM flake out like this, though.
