Do you want to probe the I2C/SMBus adapters now? (YES/no):
Using driver `i2c-i801' for device 0000:00:1f.4: Sunrise Point-LP (PCH)
modprobe: FATAL: Module i2c-dev not found in directory /lib/modules/4.13.12
Failed to load module i2c-dev.
------------------------------------------------
Of course module can not be loaded in a static kernel. IMHO detection
should not depend on that.
Is this the reason for not showing any core temps under thinkpad-isa-0000?
Why only 4 under coretemp-isa-0000?
