sounds like something's going wrong for you that isn't
going wrong
for me: dim and blank happen correctly after sleep
for me.

i haven't tested networking robustness on os13, so can't
speak to
this.
please file tickets for the problems you're seeing, and
attach
dmesg output, as well as powerd.trace. (enable powerd
tracing
with "sudo powerd-config =trace-on".)
Well, my predicament with powerd and a proper ticket filling is that I can get no logs. So
I'll describe the story instead ...:-)
Test settings SLEEP=15 DIM=30 BLANK=45 running on battery. os13 (clean). XO-1 CL1 Firmware
q2e42d(not overclocked, no SDcard or anything attached to it)
Without trace-on the XO will sleep and will _not_ dim or blank. On slight touchpad touch
after the timeouts (or spontaneous if you let it long enough) will wake to dim and then
blank. Power button wakes it up fine but no trace log.
With trace-on, same behavior but on slight touch of the touchpad (or spontaneously) will
wake to dim and freeze there. After hard reboot no trace log either :( and no I do not
have a serial port adapter)
It's a clue though (I hope)
If while at sleep, pass dim or blank time points, you wake it up by typing or rubbing the
touchpad constantly, will wake, dim and then recover to normal operation. This is where
the attached powerd.trace is coming from.
It would appear that the kernel configuration is also relevant. With the os13 kernel I
also got a freeze without the trace-on (1 in 5 tests). With the 2010322 kernel never (in 6
tests). Using one of my kernels patched for Aufs and with hfsplus, sisusbvga modules and
in-kernel loop enabled, I can not get it to sleep unless both DIM and BLANK are before
SLEEP time (I could provide config diffs and trace logs if you think it may help the issue
at hand)

hi yioryos --
thanks for the detailed descriptions.
debugging and drawing conclusions about suspend/resume
problems is pretty hard without a serial connection. i'll
try and stress an OS13 a little more, and see if i can't
reproduce your symptoms. others with serial ports are
welcome/encouraged to try as well. ;-)

okay -- this is definitely a kernel issue then. i think i thought
we'd gotten past all the bad ones, but i guess not.

hard freezes are certainly harder to diagnose.

Ok.
Also to point out that when it goes to sleep, regardless of dim or blank, will drop the
wifi connections. However, getting out of sleep will eventually (in about a minute)
reconnect.
So SLEPP is equivalent to suspend, disregarding DCON/screen state.
