100% CPU usage after resume from hibernate or suspend --- now with clue
Do you have the latest flash version installed?
(In reply to comment #1) > Do you have the latest flash version installed? Yes. the About Flash page reports: You have version 9,0,28,0 installed I had this problem with the previous version of flash, and flash v8 before that.
I've noticed this on SeaMonkey. I think the problem is that the page is using a setInterval and when you resume it runs every interval between when you suspended and the current time.
...perhaps i spoke too soon. approximately five minutes later, cpu settled down to normal. So, that's bad [there should be no cpu peg due to firefox just because i resumed], but that's better than the normal scenario, where it takes tens of minutes or hours to quiet down.
Do you maybe have an extension loaded that uses setInterval? I can reproduce this using a page with setInterval. And I don't see it otherwise. Btw, I'm using Linux. If you're sure this isn't the problem you're seeing, then I'll probably open a new bug for setInterval. :-)
Could you disable the extensions or try it with a new profile and see if it still happens?
Logged Bug 376643, making this bug dependent
BTW, to test this you don't have to go through a full Hibernate/Resume cycle; For Windows you can use SysInternals PsSuspend: http://www.microsoft.com/technet/sysinternals/utilities/pssuspend.mspx ...and for Unix you can send STOP and later CONT signals to the process. Hope this helps simplify testing
Ah sorry, I now checked the other bug and see you're already aware.
Bug 376643 was just fixed.
