Fair enough, thanks!  Thinking about it, Stephen Tweedie's ext3fs patches
would be my prime suspect.  They affect filesystem code at a very low
level AFAIK.  I'll give this another try without them applied, using the
OpenAFS afsd (never heard any opinions on whether my use of the Transarc
3.6 afsd with OpenAFS kernel module could have been problematic).
