This solution worked for me. I'm not exactly sure what I disabled, but I'll take my chances at a broken thing over a core spinning at 100% constantly.

1. find out the "gpe" that is causing the bad stuff with something like:
   $ grep . -r /sys/firmware/acpi/interrupts/

2. Check for an high value (mine was gpe08 with a value like 200K). Change the
   following accordingly. Backup the gpe file..
   $ cp /sys/firmware/acpi/interrupts/gpe13 /pathtobackup

3. Create a crontab entry to disable the gpe on reboot:
   $ sudo crontab -e
   @reboot echo "disable" > /sys/firmware/acpi/interrupts/gpe08

4. To make it work after wakeup from suspend:
   $ touch /etc/pm/sleep.d/30_disable_gpe13
   $ chmod +x /etc/pm/sleep.d/30_disable_gpe13
   $ vim /etc/pm/sleep.d/30_disable_gpe13

4a: Add this as the script in step 4:

#!/bin/bash
case "$1" in
  thaw|resume)
    echo disable > /sys/firmware/acpi/interrupts/gpe13 2>/dev/null
    ;;
  *)
    ;;
esac
exit $?
