Hmm, scratch that - the failure reappears again even with this feature disabled in bios. But apparently it only happens with usb3 hard drives. I'm completely puzzled.

After that (even if it was unmounted and removed) it becomes impossible: the system goes to suspend briefly (for bout 1 second) but immediately wakes up for no apparent reason. I suspect there's some weird bug in xfce power management - is there a way to disable it alltogether and rely on systemd directly instead? --- ApportVersion: 2.17.2-0ubuntu1.1 Architecture: amd64 CurrentDesktop: XFCE DistroRelease: Ubuntu 15.04 EcryptfsInUse: Yes Package: linux (not installed) Tags: vivid Uname: Linux 4.1.0-040100rc6-generic x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm audio cdrom dialout dip fax floppy fuse kismet libvirtd lpadmin netdev plugdev sambashare scanner sudo tape video wireshark _MarkForUpload: True --- ApportVersion: 2.17.2-0ubuntu1.1 Architecture: amd64 CurrentDesktop: XFCE DistroRelease: Ubuntu 15.04 EcryptfsInUse: Yes Package: linux (not installed) Tags: vivid Uname: Linux 4.1.0-040100rc6-generic x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm audio cdrom dialout dip fax floppy fuse kismet libvirtd lpadmin netdev plugdev sambashare scanner sudo tape video wireshark _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1454253/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
