just took the time today to try https://wiki.ubuntu.com/Kernel/MainlineBuilds to see if there is some hope for the future and maybe to get a better picture of this bug ...
i tried so far - 3.5.7 20121129 - 3.6.3 20121021 - 3.7.0rc2 20121020 conclusions: 3.5.7: same old bug, kworker never sleeps. 3.6.3 & 3.7.0rc2: after boot all looks the same, kworker running amok with 82%, several reboots and stuff wouldnt change the situation. i get a customers call and have no time for this for a while - when i come back surprise surprise kworker snores away with 0,3% cpu ... but repeated testing only raises more questions ... i got a silent (<1% cpu) kworker: - apx. one out of 5 directly after reboot - sometimes after just waiting some minutes to half an hour - sometimes after screen blanking/screen saver (= could be the time aswell) will do further testing in the matter ... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/887793 Title: Kworker constantly taking about 100% CPU To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/887793/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
