apw,
I did some data-mining on the bugs that report resume takes a long time, ie
in the order of seconds. There are 150 such bugs which I believe spans
karmic+lucid. The long resume bug#s and their resume time can be found on
http://people.canonical.com/~manjo/sr/longresume.html
The average of the long resume time is 18.141 seconds. The resume times
that are reported is the total resume time. In my patch I am printing
resume time per driver:device which is in the order of milli seconds in
most cases, and I print as I resume, so I wont be able to know the total
resume time until I fully resume. I don't think I found what I was looking
for triaging these bugs, as a result. If you look at my sample output most
devices resume in 0.001ms (on dell Mini10V), and resume took 3.880 seconds
total.

I estimate that I should print any device that takes more than 100.00 msec
to resume. This will eliminate a lot of noise from dmesg.
thoughts ?
Cheers
