Hi Nate:
I made the polling adjustment that you suggested:
sysctl hw.acpi.thermal.polling_rate=1
and then ran the script while compiling qt33 and Mozilla at the same time. the initial reading was at: hw.acpi.thermal.tz0.temperature: 3112
the high temps were:
hw.acpi.thermal.tz0.temperature: 3242
hw.acpi.thermal.tz0.temperature: 3252
the fan kicked on at 3232. I could not get the error again, even though I ran the computer under load for quite a while.
The output of acpidump -t -d > pwrnotebooks-C.asl is here:
http://www.silbsd.org/bugreports/pwrnotebooks-C.asl
it was too many lines to post to the list. Let me try a few more things with to tease out this error message again.
Kind regards
Jonathan
