Description of problem: The sensor module 'jc42' is not build/shipped. This is true for f19 and f20. I have tried building it and it works fine for me :-) Please build jc42 module.
Can you elaborate why? It's a temperature sensor, correct? Does building and using it allow you to accomplish something other than just knowing what the temperature of your DRAM is?
There was no motherboard temp, voltages and fan rpm's, so I ran sensors-detect and all I got was JC42. Sure it only showed two temp's, but what the heck, perhaps later versions .... and now you tell me its the DRAM temp, and I feel silly. THX!
