Looking at amdtemp_gettemp() there, I suspect the 0x15 family uses yet another number or placement of register bits; your ~13C to 15C range of temps shown seems much more likely to be in the ~52C to 60C range .. cc'ing jkim@, although others have messed with amdtemp more recently. acpi0: 7596MS A7596100 on motherboard # sysctl dev.amdtemp dev.amdtemp.0.%desc: AMD CPU On-Die Thermal Sensors dev.amdtemp.0.%driver: amdtemp dev.amdtemp.0.%parent: hostb4 dev.amdtemp.0.sensor_offset: 0 dev.amdtemp.0.core0.sensor0: 15.3C # sysctl -a dev.cpu | grep temp dev.cpu.0.temperature: 15.2C [..] dev.cpu.7.temperature: 15.2C I am not sure how this ^ relates to what acpi reports under thermal. I assume dev.amdtemp.0.core0.sensor0 is the source for all of those. I am not sure how correct these numbers are but I've enabled AMD's Cool'n'Quiet thingi in BIOS. Looks like you need to ask someone to add support for family 0x15. As for Eric, with no _TZ support, I don't know how you'd handle overtemps. And neither of these are reporting hw.acpi.thermal .. is it because the BIOS / ACPI doesn't present thermal zone information? I'd believe so. Or there aren't suitable drivers to interpret it? I've no idea, but does seem curious. Any output from? # acpidump -dt | egrep -i 'TZ|thermal' nothing. # acpidump -dt | egrep -i 'TZ|thermal' acpidump: RSDT entry 3 (sig OEMB) is corrupt Now this ^^ error might also suggest something is wrong. Don't know, but probably not related to the sensor temperatures. If so, you might want to put your full ASL up somewhere. # acpidump -dt | gzip -c9 amd_fx8350.asl.gz amd_fx8350.asl.gz is attached. It's no use to me and the list swallowed it; you'd need to put it up at an URL somewhere .. but as it has no Thermal Zone section it can't help with this issue anyway. By the time I collected everything, # sysctl dev.cpu | grep temp dev.cpu.0.temperature: 14.0C dev.cpu.1.temperature: 14.0C dev.cpu.2.temperature: 14.0C dev.cpu.3.temperature: 14.0C dev.cpu.4.temperature: 14.0C dev.cpu.5.temperature: 14.0C dev.cpu.6.temperature: 14.0C dev.cpu.7.temperature: 14.0C 56C most likely, unless there's also an offset.

Sorry .. I didn't look closely enough at all. The version on head does appear to support the 0x15 family as well, and quite a bit of the code has been reworked and augmented. #define DEVICEID_AMD_MISC15 0x1603 Looking at amdtemp_gettemp() there, I suspect the 0x15 family uses yet another number or placement of register bits; your ~13C to 15C range of temps shown seems much more likely to be in the ~52C to 60C range ..
