Mule,
Thanks for being so patient!  This is definitely not the experience
we want to give our customers.  We *will* resolve this problem, or
exchange your unit, (or refund -- but you don't want to do that ;-).

So, the smoking gun is this:  
Jan 1 01:00:49 kernel: [ 49.507417] i2c-adapter i2c-1: ACK not
received

That means something has gone awry with the microcontroller -- it could
be a hardware or software problem.  Shortly before release one of our
developers found a problem with interference in one room in his house,
that exposed a bug in the microcontroller IR receiver code.  We fixed
this problem, but perhaps there is another one.  The interference could
be coming from a fluorescent bulb, or some other light or RF source in
the 40kHz range.

If you would like to give it a try, I can make you a special
microcontroller firmware load to help resolve this issue.

If you are game, please give this a try:
ssh -lroot <ip-address>
# cd /sys/bus/i2c/devices/1-0010
# echo erase > flash
# echo program > flash

During the program stage, it will hang for about 5 seconds, but then
everything will come back to life, and your knobs should work again.

I'm sorry you're having problems.  We really appreciate your patience
with this. 

If you would like to give a try with new microcontroller firmware, let
me know, and I'll PM you with microcontroller update instructions. 
(it's no more difficult than the instructions above for reprogramming
the microcontroller).

Sincerely,
-Caleb
