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. ;-) paul yioryos wrote: > > Well, my predicament with powerd and a proper ticket filling > is that I can get no logs.

Power button wakes it up fine but no trace log. okay -- this is definitely a kernel issue then. i think i thought we'd gotten past all the bad ones, but i guess not. > > 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) hard freezes are certainly harder to diagnose. > > 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.
