14:25 #nouveau: < tobijk> hey there, with 4.7 nouveau started to complain about some sensor: nouveau 0000:01:00.0: iccsense: Unknown sensor type 30, power reading disabled
14:25 #nouveau: < tobijk> is this only a new debug print or is something likely to be broken? :)
14:26 #nouveau: < karolherbst> tobijk: nope, just your vbios contains something we don't expect
...
14:27 #nouveau: < karolherbst> tobijk: well, there is no harm in that message
14:27 #nouveau: < karolherbst> we can't read the power consumption on your GPU anyway
