I starting DDB and set breakpoint to rt_xaddrs $ b rt_xaddrs $ c then I do # route delete xxx.xxx.xxx. then DDB say's: Breakpoint at rt_addrs I do $ trace and receive _rt_xaddrs(...) at _rt_xaddrs _route_output(...) at _route_output _raw_usrreq(...) at _raw_usrreq ..... _syscall(...) at _syscall Bad user frame pointer: 0xXXXXXX ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1. Why I receive this ? Then I want make kernel core dump and I do (in DDB) $ panic 2. What another way making kernel dump ? Then I do (after restart my PC) # gdb -k -s /kernel.gdb -e ... -c ... gdb> bt ... rt_xaddr(...) raw_usrreq(...) ... gdb> 3. Why I can't see route_output in steck ? --- igor@blik.samara.su (Igor)
