This bug is really bugging me, because despite being upto date with everything released so far, it wont go away for me. :)
I have tried everything recommended on this thread, but the load does not come down as much as if I were to shutdown udev completely. I include a snapshot of all running process, with intermittent udev restarts, to show that the problem does not go away on my machine. As you observe in the attached file, the load drops significantly as soon as I stop udev, but restarting it at various late intervals does not change the load much. Interestingly, powertop reports this suggestion for udevd. The program 'udevd' is writing to file 'block:sr0' on /dev/devtmpfs. This prevents the disk from going to powersave mode. ** Attachment added: "udev-load.txt" http://launchpadlibrarian.net/41268255/udev-load.txt -- CD-ROM polling on some Optiarc drives causes high CPU usage https://bugs.launchpad.net/bugs/379780 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
