lkcd & kdb

[Thomas Graichen <news-innominate.bln.list.sgi.lkcd@xxxxxxxxxxxxx>]

i just patched the latest lkcd patch into the SGI XFS tree (which
also contains kdb) ... it so far also works but after it has
written the dump it panics (now into kdb) on mm/memory.c line 634

                for (j = 0; j < nlast; ppage++, j++) {
                        page = *ppage;
                        if (!page)
                                continue;
                        UnlockPage(page); <-------
                }
        }
        return 0;
}

don't know what the reason for this is - kdb or 2.4.0 kernel - so
my question: did anyone else try this so far? - any solution in
sight?

it is absolutely reproducable if anyone wants to try it - but i
can also post an backtrace of the panic here if that might help
(but it does not look very interesting i think - it ends in
kiovec_unlock or something like) ... btw. i used a simple panic
module (calling panic() in init_module) via insmod to force the
panic ...

any ideas? - thanks in advance
