safe thing to do is freeze the filesystem before suspend and thaw it after resume. This is why I originally asked you to test that with the other problemCould you add that to the XFS threads if it is really required? They do know that they are being frozen for suspend.Well, do you remember the workqueues? They are still nonfreezable.
