Bug Description

When the files and folders plug-in is activated and given a folder to index that is a mounted samba share, hibernate fails.

In my case, I had added the folder "~/.gvfs/share on server" which is equivalent to asking F&F to index //server/share

The following entries were in my kern.log after attempting to hibernate:

There were two instances of gnome-do running, one each on two separate accounts.

On disabling gvfs locations, hibernate works again.

example dmesg output from suspend failure

When trying to suspend my ThinkPad X61 laptop (via keypress, lid closure, panel menu, etc.), about two tries in three fail. Diagnostic information in dmesg and /var/log/messages refers to "Freezing of tasks failed after 20.00 seconds (1 tasks refusing to freeze)". The specific task is usually (but not always) gnome-do. The call trace varies a bit, but *always* mentions fuse_request_send called by autoremove_wake_function at or near the top of the trace.

Are you using any fuse filesystems?

In Red Hat Bugzilla #656992, Ben (ben-redhat-bugs) wrote on 2010-12-09:

I have up to three fuse-related file systems in use:

(1) This machine dual-boots Fedora and Windows 7. At all times when the machine is up and running Fedora, the main Windows 7 NTFS partition is also mounted. It is listed in /etc/fstab as having file system type "ntfs", but running "mount" shows that this is actually mounted using file system type "fuseblk".

(2) Whenever I am logged in with my standard GNOME desktop, "gvfs-fuse-daemon" is mounted on $HOME/.gvfs with file system type type "fuse.gvfs-fuse-daemon". This lasts for my entire login session.

(3) Occasionally during a login session, I may mount a remote file system via fuse's sshfs. This comes and goes; it might be mounted during some suspend attempts but unmounted during others.

Ok. Are you able to test whether the failure occurs without the ntfs and sshfs filesystems being mounted?

The failure does *not* occur with the ntfs and sshfs filesystems unmounted.

Since the problem is nondeterministic, I experimented for a few days with the ntfs filesystem mounted or unmounted. (The sshfs filesystem was never mounted.) With ntfs mounted, I had 11 successful suspends and 4 failures. With ntfs unmounted, I had 8 successful suspends and 0 failures.

All this processes was working on the zfs-fuse filesystem compiling kernel. I canceled make or git respectivly. And i could easly suspend and resume later. So quite easly reproductible.

kernel config attached.

compiled on i386, pentium-m, Debian GNU/Linux unstable. gcc 4.6.0-7. -dirty only because of changed Makefile to use gcc-4.6.

Thanks.

Interesingly, I have this problem only when STARTING compilation of kernel. Most problematic for some reason is git command (git describe --exact-match) and conf. When this commands are in progress, then i cannot suspend. But when they end, and normal compilation took place (still with pretty big disk usage), I have no problem suspending machine (10 success in 10 tries).

But when i put really big load on machine (make -j6), then also can reproduce this when compiling:

I know some time ago, there was similar problem with sshfs. One could not suspend when sshfs was mounted. But i had no such problem on zfs-fuse previously. Also on sshfs it was that no file needed to be opened or operated on, it was sufficient to have sshfs mounted to prevent suspending. Here, one need to put considerable load to trigger some kind of race-condition.

AFAIK suspending logic is not sufficient. First kernel freezes all processes, but then it tries to perform something with filesystem, probably caches, but cannot do anything as process (zfs-fuse), is already freezed.

Still present in 3.0.0-rc7, when performing simple cat /some-fuse-file-system/bigfile.avi > /dev/null.

I really do not know if this is new issues, but I had no issues for few years, and just noticed it in 2.6.39 - 3.0.0

Yes, this is a known issue with fuse vs. suspend.

In Red Hat Bugzilla #656992, Josh (josh-redhat-bugs) wrote on 2012-02-28:

There are some known issues in regards to fuse and suspend/resume. Essentially, a task stuck in the fuse layer can cause the freezer to give up and suspend will abort.

http://lists.debian.org/debian-kernel/2011/10/msg00412.html

There is work ongoing upstream for this but nothing explicit that I see in the tree yet. I'm going to move this bug to rawhide for now. In the meantime, unmount the fuse filesystems before suspending.

I got the following yesterday with the stock 3.5.0-24-lowlatency kernel of Linux Mint and also got it recently with 3.5.0-19-generic.

I bumped into this issue lately and encounter with it from time to time so this definitely seems a standing issue.

This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

Still reproducible on Linux 5.10 with debian stretch. Steps to reproduce:
- Mount something using fuse sshfs (sshfs 2.8, libfuse 2)
- Run "cat /path-to-sshfs-mount/some-big-file > /dev/null"
- Try to suspend while above command runs

Actual behavior: suspend doesn't work
Expected behavior: suspend should work
Reproducibility: always

Please, reopen the bug
