[Bug 861642] Re: upowerd uses 100% cpu till killed
Any updates? The diagnosis in comment #10 seems to make sense. This has been a problem since 2011 and I still see the same issue on Ubuntu 16.04 LTS with latests patches. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/861642 Title: upowerd uses 100% cpu till killed To manage notifications about this bug go to: https://bugs.launchpad.net/upower/+bug/861642/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

For fuller output you can add `-s 999` ... these are XML formatted messages being sent to the iPod as part of some kind of iOS proprietary communications protocol. You can verify using a USB capture via usbmon, that the host Linux system is in an infinite loop asking the iPod for something. Wireshark doesn't have a dissector for iOS vendor-specific interfaces and commands but you can see the same XML messages traveling the USB bus that were observed in strace. Is this actually a bug in libimobiledevice ? This seems like a failure to obey an iOS protocol.
