Currently being investigated. See "ppp triggers GPF panic" and "Re: r194546 amd64: kernel panic in tcp_sack.c" for other threads on freebsd-current@ that likely are the same panic (not confirmed yet though as we only have access to Kamigishi's crash dumps so far). Do you have a crash dump? Cheers, Lawrence
