coretemp6: critical temperature detected, suggest system shutdown

[mnd999]

Hi all,

The last few times I've tried to do a world build (I like to keep up with -STABLE), I've seen a number of the following messages in my syslog:

coretemp6: critical temperature detected, suggest system shutdown

I'm impatient, so I tend to do a make -j20 buildworld which does stress the system quite a lot but even so, I'm not sure I believe the messages as I haven't experienced any instability. Unfortunately, I wasn't looking at the thermal sensors at the time.

I'm running a Core i7 920, with an Asus P6T deluxe motherboard so it should be reasonably standard kit. I have the coretemp(4) and aibs(4) modules loaded, and powerd(8) running in adaptive mode. I also have the following hints, but I can't remember why.

hint.p4tcc.0.disabled=1
hint.acpi_throttle.0.disabled=1

Does anyone here have an experience in diagnosing these issues? Obviously, I don't want to melt my CPU but I'd like to get to the bottom of why I'm seeing these slightly worrying messages.

Thanks,

Mark

In my experience when the temperature gets to a critical level it will beep and display a message on the console that temperature has reached a critical level, along with the temperature it's reached (I've seen it 100C and higher), and that it's going to shut down in 1 minute, or that the temperature has gotten sufficiently high enough that it's become a safety issue for the machine components and it shuts itself down automatically.

My old laptop with a 1.2GHz Celeron and 256MB RAM would run hot with FreeBSD 9.0-RELEASE and would occasionally shut itself down while compiling a port. I even tried pointing a fan on it to keep it from overheating, which did cool it off enough to keep it from shutting down.

None of my other machines have ever gotten that hot.
