Re: Kernel Panic on FreeBSD 10.0-CURRENT #1 r253918
Can you try to update the kernel to r253950 or later? This is probably because one of my recent commits broke IPv6 temporary address timer on non-IPv6 interfaces. -- Hiroki I just built a kernel based on r253950, I will keep the list updated if the panic happens again -- Sam Fourman Jr. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org
