A workaround for my gvim-based hang is to not have gvim open on the sshfs when I suspend. I don't have that option with gsd-housekeeping, so I basically have to unmount sshfs before suspend, which breaks everything else (eg. open bash prompts). Using "sshfs -o reconnect" works fine except for this.

I use "sshfs -o reconnect" and often run gvim against a file on an sshfs filesystem. Sometimes when I suspend I get: Jul 4 20:59:08 xps kernel: [46684.608740] PM: Syncing filesystems ... done.

AFAICT, this is https://bugzilla.redhat.com/show_bug.cgi?id=656992 and https://lists.debian.org/debian-kernel/2011/10/msg00412.html has an extensive explanation. The corresponding Debian bug was closed long ago due to inactivity. It isn't exactly bug 388419 though since that is about behaviour after resume, rather than failure to suspend. This affects sshfs-fuse, but it sounds like a full fix would be in the kernel. I wonder if it's possible to work around in userspace packaging in sshfs-fuse, though, by arranging some action in userspace before suspend? It seems unlikely that this will be addressed any time soon, but it'd be nice to keep a bug open in Launchpad so that users can have a single rallying point. --- ApportVersion: 2.20.5-0ubuntu5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: robie 1519 F.... pulseaudio CurrentDesktop: GNOME DistroRelease: Ubuntu 17.10 HibernationDevice: RESUME=UUID=ae23a431-2f44-4c12-992a-a0da8186bfcc InstallationDate: Installed on 2017-05-11 (54 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Alpha amd64 (20170507) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 0bda:568b Realtek Semiconductor Corp.
