Summary: Aspire-ing to use 13 year hardware Dual boot image = /boot/vmlinuz root = /dev/sda3 label = Slackware15.0 read-only image = /boot/vmlinuz root = /dev/sda2 label = Slackware14.2 read-only First change # LILO configuration file # Append any additional kernel parameters: append="acpi=ht" Dropped CPU usage to 50% Second change grep . -r /sys/firmware/acpi/interrupts/ /sys/firmware/acpi/interrupts/gpe1D:322734808 STS enabled unmasked echo "mask" > /sys/firmware/acpi/interrupts/gpeXX Interrupts Interrupts My case was echo "mask" > /sys/firmware/acpi/interrupts/gpe1D Dropped usage to 0-5% Then added the mask to crontab -e under root Add 'acpi_mask_gpe=0x1D' or whatever interrupt corresponds to the overactive one, and remember to run the lilo command afterward to make the kernel option active.
