    Where does the system hang?  Is there a reference code for the hang?  Boot the system to open firmware and do a debug boot.  Do the following

     

    printenv boot-device

    boot <boot-device> -s trap

    then press g at the KDB prompt and note where the system hangs (log your session)

    Joseph,

    Thanks for the reply... the system boot normaly, mount all the file systems, start swap spaces, start network services... but, a few seconds after... the system hangs... the system doesnt show errors in errpt, let me try your recomendations.

    I did not think the system was booting all the way up so I thought it may hang during reboot.  Since it does boot up, you'll want to enable the debugger so that when the hang happens you can hot-key into the debugger.

    Do these commands before typing g and the kdb prompt

    mw enter_dbg

    42

    .

    mw kdb_polling

    1

    .

    then press G

     

    Then when the hang happens to a ctrl-\ to get into KDB, there you can look at the system

     

    Hangs are harder to debug than a crash.

     

    When you hot-key into kdb the systems stop.  Before  you do this, try to ping the system from another machine. If successful, the system is handling interrupts.

    Try telneting into the system from a remote location (assuming telnet is enable) and ping works.

    Once you hot-key into KDB, post results of

    vmstat

    stat

    status
