Solved coretemp2: critical temperature detected, suggest system shutdown

[rsronin]

Somebody encountered this before/too?

amw@t430 ~> sysctl -a | grep temperature
coretemp2: critical temperature detected, suggest system shutdown
hw.acpi.thermal.tz0.temperature: 48.1C
dev.cpu.3.temperature: 52.0C
dev.cpu.2.temperature: 52.0C
dev.cpu.1.temperature: 51.0C
dev.cpu.0.temperature: 51.0C
amw@t430 ~>

I am on a Thinkpad t430 with an Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz.

amw@t430 ~> freebsd-version -kru
13.1-RELEASE
13.1-RELEASE
13.1-RELEASE

It happened both with and without bsdfan.

48-52(C) is really not bad. Odd that it is giving an alarm.
New problem since 13-1 upgrades perhaps? Definatly ACPI or coretemp2 related.
I do sysctl -a|grep temp alot and have never seen that.

What exactly are you asking here?

If the question is simply "is that possible", then yes, temperature got over the threshold and driver printed a warning, and I have seen it previously.
If the question is "why did it print the warning when temperatures are normal in the output" -- don't forget that sysctl -a output includes the entire kernel message buffer, and the message was likely printed some time ago.

The message went away after a reboot.
