Never mind, you gave me enough here I could just pipe it through sort and get: c01a3a34 T ipip_input c01a3a48 T _ip_mcast_src c01a3a50 T ip_rsvp_vif_init c01a3a5c T ip_rsvp_vif_done c01a3a68 T ip_rsvp_force_done c01a3a70 T ip_output c01a49ec T in_delayed_cksum c01a4a64 t ip_insertoptions c01a4c44 T ip_optcopy I was wrong, it is not in ip_input, it is in ip_output. > > (gdb) x/10i 0xc01a44cb > 0xc01a44cb <ip_output+2651>: incl 0x28(%edx) > 0xc01a44ce <ip_output+2654>: mov 0xffffffcc(%ebp),%eax > 0xc01a44d1 <ip_output+2657>: mov 0x18(%eax),%eax > 0xc01a44d4 <ip_output+2660>: add %eax,0x38(%edx) > 0xc01a44d7 <ip_output+2663>: mov 0x10(%ebp),%ecx > 0xc01a44da <ip_output+2666>: pushl (%ecx) > 0xc01a44dc <ip_output+2668>: pushl 0xffffffd4(%ebp) > 0xc01a44df <ip_output+2671>: pushl 0xffffffcc(%ebp) > 0xc01a44e2 <ip_output+2674>: mov 0xffffffbc(%ebp),%ebx > 0xc01a44e5 <ip_output+2677>: push %ebx > (gdb) > Hummm... did you get a crash dump? Or can you. If so a gdb backtrace would be most helpful. -- Rod Grimes - KD7CAX @ CN85sl - (RWG25) rgrimes@gndrsh.dnsmgr.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
