      I ended up finally getting it to work!  I contacted Fit-PC support (they make the Fitlet iA10) and they mentioned that amdtemp.c had to be built with 2 extra lines in it.  Here is the URL that details the fix in the code.  Basically, 2 lines have to be added to amdtemp.c, then the kernel has to be recompiled with the new amdtemp.  I tried recompiling amdtemp.c by itself, but couldn't figure it out.  I'll include the steps I followed in case anyone else wants to try, and I'll see if I can attach the new amdtemp.ko files.

      • Install FreeBSD 10.1 amd64 on a machine (I put it in a VM) and get it connected to the network

      • Download the kernel source

      # fetch ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/10.1-RELEASE/src.txz
# tar -C / -xzvf src.txz

      • Add two extra lines of code to /usr/src/sys/dev/amdtemp/amdtemp.c per the article above (see attached as well)

      • Modify custom kernel config to compile new amdtemp

      # cd /usr/src/sys/amd64/conf 
# cp GENERIC CUSTOM
# vi /usr/src/sys/amd64/conf/CUSTOM
add line to end of CUSTOM file: device amdtemp
      • Build the kernel (this takes awhile based on machine CPU)
      # cd /usr/src
# make buildkernel KERNCONF="CUSTOM"
      • Install new kernel files
      make installkernel KERNCONF="CUSTOM"

      • You should now have a new amdtemp.ko file in /boot/kernel on your FreeBSD 10.1 installation

      • Copy new amdtemp.ko file to pfSense with scp, sftp, usb or some other method (copy file to /boot/modules)

      • If you can get into the pfSense shell, you can load the module

      # kldload /boot/modules/amdtemp.ko
      • Enable AMD temp sensor in pfSense console:  System > Advanced > Miscellaneous : Thermal Sensors section

      Now if you add the Thermal Sensor applet to the dashboard, it should show up:

      If you don't want to go through all that, attached are the updated amdtemp.ko files.  I'm including the files for FreeBSD 10.1 and 10.2 (for when pfSense upgrades).  Just rename the file amdtemp.ko.10.1.jpg to amdtemp.ko for example.

      amdtemp.c.txt
      amdtemp.ko.10.1.jpg
      amdtemp.ko.10.2.jpg

        You might want to submit this upstream to FreeBSD, so the change/fix can be included in their code, and will then flow downstream to pfSense and other projects that use FreeBSD.

        BTW, pfSense 2.3 will be using the just released FreeBSD 10.3, not 10.2.

            According to the FreeBSD Release Page, 10.3 was going to be released at the end of March 2016.  But only RC3 is available now.  Once stable is released, I'd imagine pfSense 2.3 work could really ramp up.  Aren't they working on a console redesign/modernization too?

              Just to answer your question, not meaning to steer this topic astray…

              pfSense 2.3 is in RC stage right now... it's VERY sharp looking (I've been running the betas for over a month on my primary box)... The FreeBSD version line in the pfSense RC is "FreeBSD 10.3-RELEASE". So it may not be stable yet, but it's very close I'm sure.

                I just upgraded to pfSense 2.3 tonight (which was easy, flawless, and without issue).  However, the temp sensor readout broke again.  It looks like the amdtemp fix didn't make it into FreeBSD 10.3.  So I recompiled the FreeBSD 10.3 kernel and got a new amdtemp.ko file.

                • Unload the module first: kldunload amdtemp.ko

                • Rename the attached file to amdtemp.ko and copy it to /boot/kernel/amdtemp.ko and /boot/modules/amdtemp.ko

                • Load the module: kldload amdtemp.ko

                • Test sensor from command line: sysctl -a | grep temperature

                • Enjoy the new Temp Sensor readout

                  How is your CPU temp so low ?
                  I have the fitlet-X and it idles at 54 C.

                    I purchased the heatsink for the i-A10, and also have it sitting on a "rack" I built with a low RPM, 80mm fan blowing on it  ;D

                      LOL nice !
                      Was kinda hoping you had some BIOS trickery going on to cool it so much.
                      I already installed the heatsink, it did cool it a bit, but…meh.
                      54-56 isn't too bad. I'm hoping it doesn't mess with the mSata SSD in there.

                      I guess I could hack a usb powered fan, but that would negate the low-power aspect of this machine.

                        I think it should be good up to 70°C.  The fan is connected to a USB port on the wifi access point, so the power consumption doesn't count against the Fitlet  :P

                          Any performance figures for this interesting cpu setup? Routing throughput & openvpn?

                            Thanks Fahrenhe1t for the help  :). Mine is working great now… It's nice to have temp readings...

                              I have a Netgear Nighthawk router plugged into the Fitlet pfSense box using bridge mode.  I use that as my wifi access point.

                              Between two wired boxes connected locally there, using iPerf3, I get close to theoretical max throughput:

                              
$ iperf3 -c fitlet -f m -n 1024M

                              I don't have a stellar Internet connection (Comcast, 170Mbps down/12Mbps up) but I'm able to get those speeds through pfSense with xfinity speedtest:

                              I have OpenVPN setup…I'll try and get on wifi somewhere else and do an iPerf while VPN'd in.

                                That test tells us the switching speed of your night hawk  :)
                                If possible you should setup an additional interface on the firewall on its own subnet, plug a pc into that and measure with another pc on the lan/different subnet.
                                You could then probably enable an openvpn server on this new interface, connect to that from a pc/openvpn-client  then do a speed test to a client on the lan.

                                    Using AT&T 4G, I VPN'd back home.  I have iPerf3 running on another box internally and ran a test.  I got 3.61 Mbits/sec.

                                    Connecting to a wifi network with 10mbps up and down, I ran the test again and got 8.47mbps.  I'll see if I can find a faster wifi network to test on.

                                    **Update, got 17.9mbps connecting back to VPN on a friend's wifi with 40down/20up.

                                        Thanks for the heads up, mine just did the same thing on 2.3.1 (not to be confused with 2.3_1  :o)

                                            I just did, and had to reload amdtemp.ko.  I ended up writing a shell script to copy the files and enable the service.
