I have seen this problem, yes.  Specifically, it has shown up when I try
to mount a JFFS2 filesystem as the rootfs.  When mounting it as a
non-rootfs, I haven't seen the problem.  I doubt that really makes a
difference though, and it's probably related more to timing than
anything.

I haven't figure it out yet.  My particular case never has the resume
code called, so I'm not sure that's the problem.
