Stress testing suspend on Linux

Here’s a script you can use to stress test suspend on Linux:

#!/bin/sh

# Watch kernel logs for the word `corrupt`
dmesg -w | grep --color -i corrupt &

echo "Starting stress test in 5 seconds..."
sleep 5

# Stress test by repeatedly putting computer to sleep for 10s
for i in $(seq 100); do
  echo "Iteration #$i..."
  rtcwake -m mem -s 10
  sleep 10
done

Save the file as stress-test-suspend.sh, then run:

$ chmod +x stress-test-suspend.sh
$ sudo ./stress-test-suspend.sh

The idea comes from the page Best practice to debug Linux* suspend/hibernate issues.
