After mounting; Doing 1 or 2 ls, works fine. However if you do a cat * >
/dev/null, it oopses.

I'm not sure if this is the real evil-doer since it spews a couple of oopses
out of scrollback reach, but the last point appears to be in d_lookup, in
the for.

        0xc013bfc6 <d_lookup+98>: movl 0x0(%ebp),%ebp

which I'd say is.

        tmp = tmp->next;

with ebp 0xaedcffd, ebx 0xaedcfe5 ; (at the end of the for

        0xc013c044 <d_lookup+224>: leal 0xffffffe8(%ebp),%ebx
        0xc013c047 <d_lookup+227>: cmpl 0x10(%esp,1),%ebp
        0xc013c04b <d_lookup+231>: jne 0xc013bfc6 <d_lookup+98>
)

If neccessary, I'll hand copy it.
