Hi.
Unfortunately I have never seen that, but I'll try to look harder. Could
you please tell a bit about your controllers/devices? What triggered the
issue?
If you still have the full dumps, could you check values of ccb_h,
ccb_h->cbfcnp, ccb_h->path and ccb_h->path->periph for the "deadcode"
somewhere or something?
