OK, I see what's going on.   i_blocks_hi is getting set to 0xFFFF.

So I definitely see the bug in e2fsck in not reporitng and fixing the
problem (and I'll fix that).  I'm not sure how i_blocks_hi got set to
that value, though; it looks like everything should be doing the right
thing in the latest mainline kernel.  What version of the kernel are
you using?
