Hi, I have a Sony with an ASUS P4B266 motherboard which is on the blacklist for incompatible BIOSes. dmesg shows "ASUS P4B266 detected: force use of acpi=ht", if I understand correctly ACPI gets disabled because of the motherboard type and force=ht has to do with enabling support for hyperthreading? I would like to make use of ACPI to control my fan speed (it has two speeds, but right now keeps running at the highest all the time). Can I force ACPI to stay on or would this cause some badness? Thanks in advance for any advice you can offer, ~ Jakub - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
