Jon,
re: comment #13
if you succeed in overriding the trip point, your setting
will be visible in /proc/acpi/thermal_zone/*/trip_points

in the case of thermal.nocrt, the trip point is unchanged,
but the trip action is ignored.

In the case of thermal.crt=-1, the trip point will simply
vanish from the files above.

in the case of thermal.crt=N, it will be set to N
The change here is the ability to make N higher than the BIOS default.

The problem with reasoning "bumping up critical is less dangerous
than disabling critical" is that bumping up the critical
trip point may actually just give you the illusion of control
that you don't actually have.  ie. the EC decides when/if
to send a thermal event which is what we use to compare
the temperature to the trip points.  There is absolutely
no assurance that the EC will do this near the new
fake trip point.

and...

"The greatest obstacle to discovery is not ignorance -- it is the illusion of
knowledge."

so i don't really like it, but i'll apply the patch in commment #7
to 'keep the customer satisfied':-)
