Thanks.  Then this happen after print_uptime().

I believe one of the drivers register a shutdown_final (or
shutdown_post_sync) event that hang your system.  I think (though I
may be wrong) mfi may be that one.

It would help if you can add some printf in dev/mfi/mfi.c into the
mfi_shutdown() function in order to check if that assumption
is correct.
