Comment 5 for bug 331415

This is a small shell-script that can help identify whether a system is affected by this bug.

for log in /var/log/kern.log*; do CMD="cat "; echo $log; [ ! ${log##*.gz} ] && CMD="zcat "; $CMD $log | grep -n 'PM: \(suspend\|resume\) devices took'; done

Example output:

var/log/kern.log
/var/log/kern.log.0
3678:Feb 19 06:06:56 hephaestion kernel: [60285.296215] PM: suspend devices took 3.752 seconds
3830:Feb 19 06:06:57 hephaestion kernel: [60354.780958] PM: resume devices took 69.072 seconds
3948:Feb 19 10:19:23 hephaestion kernel: [75478.752211] PM: suspend devices took 3.752 seconds
4102:Feb 19 10:19:23 hephaestion kernel: [75488.172580] PM: resume devices took 9.024 seconds
/var/log/kern.log.1.gz
/var/log/kern.log.2.gz
/var/log/kern.log.3.gz

The resume of 69 seconds shows this system is affected.
