I tried to eliminate that early on by doing tests back to back (expecting heat would make the failures come faster), but that didn't seem very promising. Sean Lazar aimed me at "sysctl hw.acpi.thermal" under 5.2 so I ran that in a sleep loop on another TTY and killed the system again with buildworld. I'm assuming that the temperature shown is Kelvin * 10. Sitting at the BIOS, CPU is ~38 degrees Celsius and system is 31. Not quite sure which one ACPI is getting, but seems closer to system. In any case, temperature measurement goes from 3002 to 3202 before freezing (10 second increments), or about 27.05 Celsius (300.2 Kelvin) thru 47.05 Celsius (320.2). The system looks like it thinks high temp kicks in at 68 Celsius. At the moment, I can't lay my hands on any CPU documentation that says what the optimal temperature range is.
