I would insert a panic() call somewhere in the beginning of nd6_llinfo_settimer(), but there is a problem. nd6_llinfo_settimer() is called not only when I start ppp, but at bootup too (at bootup - once, I think that this is due to initializing lo0 interface, which has a default ipv6 address). Could I somehow make the kernel not panic at boot time and panic later, when I call ppp? E.g, how can I know uptime from the kernel mode? -- WBR, Victor V. Snezhko EMail: snezhko@indorsoft.ru
