Resulting cores are identical in sense > that I can't analyze them ;( I get the "wrong dirclust" panic once, I have a small kgdb session in this thread [1], this might help, although the panic was triggered from mkdir(2). Unfortunately, I don't have the dump anymore, it consumes too much space to keep all unresolved panic dumps :(.
