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) > > paul > > > > in DIM=180, BLANK=480, SLEEP=600.
