would it be ok if you test a 3.0 kernel to see if suspend is more reliable? I made some changes which maybe improve resume (in fact, the .38 code always failed to resume in 3.0, so it needed a fix). > Also, I noticed that in the syslog there are some ec commands logged, I > figured it might be helpful for someone who is more familiar with them, > so I attached the syslog (trimmed to start from the resume) These look harmless. Seems the EC sends power on events. Maybe we need to ack them to let them go away. I may take a look at it later on. > And now that I'm going on about suspend, at some point the close lid > didn't even suspend reliably, so I sometimes suspended from the menu, > but as I was doing that in train just when my stop comes, I'm in a hurry > and close the lid anyway, and next time it resumes (succesfully), it > goes to suspend immediatelly again, so there is some double standby > action going on there. > (and I think I once saw a double modulated standby-led-blink) mmh, I just checked it here on 3.0 and it worked as expected. So again, can you please test with janimos kernel?
