Well, I don't either, because we don't freeze processes on powerbooks. But I have heard that other people have problems with suspending with a fuse filesystem mounted. Maybe the difference is whether or not the filesystem is writable?

It's not the filesystem sync method, as I understand it, it's that if there are dirty pages in the page cache for files on the fuse filesystem, the system will initiate a write-out on them and wait for it to finish. But if the fuse userspace is frozen, the write-out will never complete.
