CORETEMP(4) BSD Kernel Interfaces Manual CORETEMP(4)NAME
coretemp -- device driver for Intel Core on-die digital thermal sensor
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device coretemp
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
coretemp_load="YES"
DESCRIPTION
The coretemp driver provides support for the on-die digital thermal sensor present in Intel Core and newer CPUs.
The coretemp driver reports each core's temperature through a sysctl node in the corresponding CPU device's sysctl tree, named
dev.cpu.%d.temperature.
SEE ALSO sysctl(8)HISTORY
The coretemp driver first appeared in FreeBSD 7.0.
AUTHORS
The coretemp driver was written by Rui Paulo <rpaulo@FreeBSD.org> as part of a Google Summer of Code project. This manual page was written

ICHWD(4) BSD Kernel Interfaces Manual ICHWD(4)NAME
ichwd -- device driver for the Intel ICH watchdog interrupt timer
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device ichwd
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
ichwd_load="YES"
DESCRIPTION
The ichwd driver provides watchdog(4) support for the watchdog interrupt timer present on all Intel ICH motherboard chipsets.
The ICH WDT counts down in ticks of approximately 0.6 seconds; the exact value depends on hardware quality and environmental factors. Sup-
ported watchdog intervals range from 2 to 63 ticks.
Note that on some ICH-based systems, the WDT may be present but disabled, either in hardware or by the BIOS. The ichwd driver attempts to
detect this condition and will refuse to attach if it believes the WDT is disabled.

Using the Intel ICH Family Watchdog Timer (WDT), Intel Application Note AP-725, Document Number 292273-001.
HISTORY
The ichwd driver first appeared in FreeBSD 5.3.
AUTHORS
The ichwd driver was written by Wm. Daryl Hawkins <dhawkins@tamu.edu> of Texas A&M University and Dag-Erling Smorgrav <des@FreeBSD.org>.

Is it possible to have a bash script pick the highest and lowest values of four variables? I've been googling for this but haven't come up with anything. I have a script that assigns variables ($c0, $c1, $c2, and $c3) based on the coretemps from grep/sed statements of sensors. I'd like to also... (5 Replies)
Hello,
I have a Toshiba Satellite A505-S6965. My hardware is as attached via the Hardinfo report in pdf format.
Here is the most recent kernel error. It never says it is shutting down. It just "dies" even after saying the temp/speed is normal.
