Comment 9 for bug 763986

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.

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.
