[issue1449] AHCI panic on Intel 6321ESB AHCI

[Matthew Dillon]

:    See if you can get the messages before the crash backtrace (see if
:    you can get a crash that does not have a secondary NMI crash which
:    scrolls the extra information I printed out off the screen).

    Also see if you can get anything more out of it with a verbose boot.
