Re: [issue713] shutdown freeze and forced unmounts

:No more forced unmounts...Cool.

:>     Lets see if that fixes your freeze too.

:Unfortunately, it still freezes after the Uptime: message.  I've tried this
:with and without ACPI.

:Any other ideas?

    I think so :-).

    Start adding kprintf()'s to the kernel in the code paths after the
    Uptime message is printed.  In paricular, the device shutdown
    path (device_shutdown() line 1198 in kern/subr_bus.c).  Also boot
    with verbose mode so the shutdown is verbose too.

    Now that we've gotten one issue out of the way at least, is it
    possible to break into the debugger after it freezes or is that still
    a no go?

    Another thing to try, drop into single user by killing init
    i.e.  'kill 1', do a ps to make sure everything has been killed
    (the only user processes left should be init, -sh, and your ps),
    and then see if a reboot freezes the system.

    It's got to be something stupid simple.  Literally.  The shutdown
    got through all the hard stuff already.  It's like it can't reset
    the cpu or something.
