I see no ill effects running for few hours with it... but if your computer melts down, please, do not blame me ;) Patch was made against -CURRENT, and I don't have access to the 6.0 machine, so you might need to tweak it manually to apply. The problem, as I see it, is that FreeBSD assumes that your fan status matches your temperature, which, apparently, is not the case. I would recommend looking for BIOS updates if any available. I will take closer look at your ASL as time permits, but not being ASL guru, could not promise much. Maybe someone more knowledgeable would chime in. -- Alexandre "Sunny" Kovalenko (Олександр Коваленко) --Boundary_(ID_SQnZW6KkNDDZkPkvuJozbQ) Content-type: text/x-patch; name=acpi_thermal.c.patch; charset=ASCII Content-transfer-encoding: 7BIT Content-disposition: attachment; filename=acpi_thermal.c.patch --- /usr/src/sys/dev/acpica/acpi_thermal.c Sat Oct 15 12:05:34 2005 +++ acpi_thermal.c Sat Oct 15 12:11:28 2005 @@ -492,8 +492,11 @@ newactive = sc->tz_active; } - /* Handle user override of active mode */ - if (sc->tz_requested != TZ_ACTIVE_NONE && sc->tz_requested < newactive) + /* Handle user override of active mode, allow user to turn on fan even + * if it is not necessary. + */ + if ((sc->tz_requested != TZ_ACTIVE_NONE && sc->tz_requested < newactive) || + (sc->tz_active == TZ_ACTIVE_NONE && newactive == TZ_ACTIVE_NONE)) newactive = sc->tz_requested; /* update temperature-related flags */ --Boundary_(ID_SQnZW6KkNDDZkPkvuJozbQ)--
