[Colin Law <1504420@xxxxxxxxxxxxxxxxxx>]

After several weeks running with the suspend command
sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend"
with both the latest mainline kernel I was unable to make it fail.  I reverted to the current kernel and it still refused to fail.  I then resorted to just using pm_suspend (with current kernel) and it did fail.  I don't know whether it is necessary to have 
echo 1 > /sys/power/pm_trace
on every suspend but from dmesg > dmesg.txt I see
$ grep -i "hash matches" dmesg.txt 
[    2.322145] bdi 1:12: hash matches
[    2.322151] tty ttyS14: hash matches

Suggestions on what I should do next please?
