[ltp] Is it just me or is ACPId way, way too verbose?

So, it probably is thermal protection. Might be that when the CPU
reached over 100C (which is forbidden by Intel, and should automatically
cause thermal throttling!), Linux was not yet ready or configured to
handle a P state change and react properly to it. You might need to have
acpi_cpufreq loaded.

On this list, there have been several reports of people who have
successfully cleaned their fans and got a big improvement in thermal
behaviour.
