Problem Description:

Steps to reproduce:

Long story short, I need to adjust my trip points to make my machine usable. 
The passive cooling kicks in at 50 slowing my computer to a crawl and it shuts
off at 60 - during the summer with A/C on it still runs 55-60 most of the time.
 I'd give you an acpidump but I don't have it on my machine and I'm afraid
getting it and compiling it might actually overheat my computer and cause a
shutdown.


[root at brybox THRM]# cat /proc/acpi/thermal_zone/*/*
0 - Active; 1 - Passive
<polling disabled>
state:                   passive 
temperature:             57 C
critical (S5):           60 C
passive:                 50 C: tc1=4 tc2=3 tsp=60 devices=CPU0 
active[0]:               50 C: devices= FAN 
[root at brybox THRM]# 


Just for reference, my computer has been running just fine for over a year with
this command in my rc.local:
echo 75:0:64:64:85 > /proc/acpi/thermal_zone/THRM/trip_points


I'll see if I can get an acpidump and update this but count my machine as one
affected by the locking of trip point values.  Let me add that the process for
changing the damned things is so arcane that you're unlikely to change them
without a lot of investigation and learning in the first place.
