I'm relatively confident that we're processing an unmapped mbuf, and that's why we're panicing here. Mark taught in_cksum_skip() to handle those, but I think in6_cksum() doesn't handle them. So we either need to insert an mb_unmapped_to_ext() call in in6_cksum(), or we need to teach in6_cksum() to deal with unmapped mbufs. -- You are receiving this mail because: You are the assignee for the bug.
