Look at the archives this is a reported problem (and fix) with the
fxp driver (new or old). Pppoe tries to send packets using the
fxp driver when the interface isn't up yet. This causes a panic
in the fxp driver.
I am not in a position to generate diffs for the fix but you
want to add:
/*
* Don't send anything unless initialized.
*/
if ((ifp->if_flags & IFF_UP) == 0)
return;
to the fxp_start() function like below to get around this problem.
static void
fxp_start(struct ifnet *ifp)
{
struct fxp_softc *sc = ifp->if_softc;
struct fxp_cb_tx *txp;
/*
* Don't send anything unless initialized.
*/
if ((ifp->if_flags & IFF_UP) == 0)
return;
