I get the same problem as Zoran's original post. My issue, after enabling the kernel module in loader.conf and rebooting, I don't see the temperature sysctl values. Fresh 9.1-REL, amd64 (ISO Image, not yet updated from 9.1-REL head) AMD A8-5500 CPU, full dmesg can be found here: http://www.nycbug.org/?action=dmesgd&dmesgid=2450 I was thinking of compiling-in "device amdtemp" this weekend- anyone know of anything else I can do to help provide a clear and easily reproducible test case?
