A new image built with slightly different variables (size, contents, etc) usually yields a filesystem that behaves correctly. But once they have a bad one, it breaks on resize every time. Let me know if I can provide any other information. I have access to the machine for some time, so I can run a modified kernel or module and post results if that would help. Thanks, -- Jon
