Re: (fwd) Re: powerd on XO-1 (was Re: New release ... OS13 )
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.

So SLEEP basically drops connections and then the XO-1 fails to DIM or BLANK. Setting SLEEP time _after_ DIM and BLANK has the expected behavior. In all cases the XO fails to reconnect to the preferred network after wakeup from SLEEP. I settled in DIM=180, BLANK=480, SLEEP=600.
