I know it's bad etiquette to reply to your own posts but nobody else has! :-) I've found a workaround for this - an S3 suspend/resume seems to reset the fan to its normal behaviour (only cutting in when the machine gets hot). The problematic sysctl entries are unchanged: hw.acpi.thermal.tz0.active: -1 hw.acpi.thermal.tz0.thermal_flags: 0 hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 I've put the dmesg output (with ACPI_DEBUG) taken after hibernation at http://zanussi.netcraft.com/acpi/ Hope this helps, jez -- Jeremy Prior <jez@netcraft.com> http://www.netcraft.com/ Netcraft Ltd, Treenwood Ho, Rowden La, Bradford-on-Avon, BA15 2AZ.
