Fan remains on, sysctl shows: hw.acpi.thermal.tz0._ACx: 80.0C 65.0C -1 -1 -1 -1 -1 -1 -1 -1 only way to get fan to shut off is to run something that will get CPU temperature to above 80.0C, then when it falls below 65.0C, the fan finally shuts off. >How-To-Repeat: Keep rebooting a laptop until it boots while CPU fan is spinning. Don't run any processor intensive applications, fan will remain turned "on" indefinitely. Same bahavior on various hardware, just reproduced with Dell l400 laptop before submitting PR. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
