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?
