Script to detect if the Intel i915 graphics card is sick or not. Watch the line about "RC6 residency since boot: NNNNN". If that number doesn't change, then your graphics card is about to go into thermal meltdown

debugi915.sh

#/usr/bin/sh
function dump_params {
echo -n '# param enable_hangcheck=' ; sudo cat /sys/module/i915/parameters/enable_hangcheck

}
declare -i secs
declare -i last_secs

echo '# ************************************** Debug File Start **************************************'
dump_params
last_secs=`date '+%s'`
while true 
do

cat /sys/kernel/debug/dri/0/i915_drpc_info

last_secs+=5

if [ $secs -gt $last_secs ] ; then
  echo '# -------------------------------------- Suspend/Resume Detected --------------------------------------'

done

This is what I got:
