There is a known bug in netinet6 that might cause this behaviour (although, I didn't see reboots, only panics). The fix is known but has not been committed yet. Here it is: --- netinet6/mld6.c Wed Nov 9 08:27:14 2005 *************** *** 640,645 **** --- 640,649 ---- mld6_stop_listening(in6m); ifma->ifma_protospec = NULL; LIST_REMOVE(in6m, in6m_entry); + if (in6m->in6m_timer != IN6M_TIMER_UNDEF) + mld_stoptimer(in6m); free(in6m->in6m_timer_ch, M_IP6MADDR); free(in6m, M_IP6MADDR); } > I didn't see this a month or two ago afaik, though it has been a while > since I had to use ppp on either laptop. The bug I mentioned was committed on Oct 21. If the fix don't help, try to disable INET6 and see if that helps. -- WBR, Victor V. Snezhko EMail: snezhko@indorsoft.ru
