      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
iPerf Client

                    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.

                            Just upgraded to 2.3.1 and temp widget is broken again… :(
                            redid your procedure and it's back...  :)

                              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.

                                    Wish they would include your mod. 2.3.2 time….

                                      Same.  I think FreeBSD has to include it in their release though.  Someone else already submitted a bug (https://lists.freebsd.org/pipermail/freebsd-bugs/2016-February/066274.html); not sure how to get FreeBSD to include the fix in a release though…

                                        Fahrenhe1t, I'm running pfSense 2.3.2p1 w/ A6-5400K CPU with set to AMD and dashboard temps read 0C to 1C, varies. No where close to accurate.  So tried your recompiled 10.3 amdtemp.ko file. Didn't change anything. My two other boxes with Intel CPU and A6-6400K work fine without a modified amdtemp.ko file.  Ideas, mistakes I may have made?

                                          Strange!  From the command line, what does the OS report if you run this: sysctl -a | grep temperature

                                            dev.cpu.1.temperature: 0.0C
                                            dev.cpu.0.temperature: 0.0C

                                            Same as before the modified file was copied to the box.
