Peter: I am not sure what you mean.. :-) The in6_lltable_lookup() is right at the line where the code has done: LLE_WLOCK(lle); lle->la_flags |= LLE_DELETED;<----- Now without seeing the registers and having a bit more details I can't say. My guess is lle is NULL or 0xdeadcode.. If so this may be a different reference counting bug.
