For example, the _CRT (critical trip point) for GFXZ tries to index into
\_TZ.TRIP  in the GETP() method and ARG0 in this call references element
6 in a 2 element package, which results in a failure.  So I guess a
bunch of critical trip points are all invalid, which may mean your CPU
is scaled down to the lowest speed.

What does the following output?

 for I in /sys/class/thermal/thermal_zone* ; do echo $I:; cat
$I/trip_point* ; done
