Hello, I got a kernel panic in ip_reass_ttl_decr() when my NetBSD-1.6ZI receives IP fragments. I think it is related to the loop for (i = IPFRAGTTL, median = 0; i >= 0; i--) { where i was declared unsigned. I use following fix that seems to work: < u_int i, nfrags, median; --- > int i; > u_int nfrags, median; Jean-Mickael
