Bug Description
Currently, coretemp driver supports up to 32 cores/socket, while KNL has up to 72 of them, in which case, the following error is printed when coretemp driver is initialized on KNL:
[ 23.399792] coretemp coretemp.0: Adding Core 1 failed
[ 23.399806] coretemp coretemp.0: Adding Core 2 failed
[ 23.399813] coretemp coretemp.0: Adding Core 3 failed
[ 23.399819] coretemp coretemp.0: Adding Core 4 failed
[ 23.399825] coretemp coretemp.0: Adding Core 5 failed
etc
Platform: KNL
This is fixed in 4.4 kernel with:
cc904f9 hwmon: (coretemp) Increase limit of maximum core ID from 32 to 128.
