In principle, it might be that
d_find_alias()is broken. I don't see where it could happen, but then I'm half-asleep right now... While we are at it, do you have

I saw oopses in prune_dcache() during umount() of ncpfs circa 6 months ago. As I was never able to reproduce problem, and it just stopped from happenning as unexpected as it appeared, I never reported that. And ~2 times I got endless loop in d_prune_aliases() where it somewhat happened that d_alias list looked like
1 -> 2 -> 3 -> 4 -> 2 -> 3 -> 4 ... (maybe after pruning d_count = 0
entries...)
so it never stopped :-( But it really happened long long ago, I think that sometime June-September 2000, and couple of logic changed since then in both ncpfs and vfs.
