Comment #13 on issue 21470 by balazs.racz: computer takes long time to wake up from sleep when chrome is open http://code.google.com/p/chromium/issues/detail?id=21470
I've been having this issue for a long time. Despite not having been able to figure out chrome might be the cause, I have some input data. 1) The delay always happens before windows turns the screen on. 2) I always have two gmails (corp and private) and a google calendar open in my chrome. I would focus on one gmail and one google calendar tab as the reproducing scenario. 3) I always have a flash plugin running. 4) there is minimal/no disk activity during the delay [i.e. disk led flashes no more often than any normal use], so it is definitely not swapping or disk-thrashing 5) delay happens both when waking up from sleep and when waking up from hybernate 6) the delay length is roughly linear in the time the computer spent in sleep mode. The rate is about 1 minute per day. I think the last is the key observation here. My guess at the problem is the following: - some javascript in an open tab has a periodic timer event - chrome wakes up, realizes that N timer events are pending - chrome executes N timer event. - for some weird reason this blocks the computer from waking up - potentially by hogging the CPU, but may be some serialization problem, like the event driver is waited for in a sequentially executed OS thread (for example one that sends power-state notifications). Due to 6) this bug takes very long to reproduce -- you'd have to wait one day for any reproducing try. THe delay is not observable on short sleeps (10-30 sec for an overnight sleep). I recommend the following procedure: - disable NTP client - open chrome, open gmail and google calendar - put the machine into _hybernate_ mode - turn the machine on, enter BIOS setup - change date to two to four days in the future - let windows resume from hybernation - observe delay. hth, Balazs -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
