Ah. The Original Maintainer, Gunter Groeck at GitHub suggested (before he tore out the repo):
“dmesg will most likely show you that you have a resource conflict. See acpi_enforce_resources or ignore_resource_conflict module options.”
if:
modprobe it87 ignore_resource_conflict=1
works, then create /etc/modprobe.d/it87 and add:
options it87 ignore_resource_conflict=1
I’ve also had the module get removed after kernel updates on some (but not all) systems, likely due to some magic setting missing and when this happens I have to:
make clean; make; make install (the module)
/sbin/ldconfig
modprobe it87
service lm_sensors restart
service snmpd restart
