:    I'm not sure what is going on there but get the latest git and try
:    again.  It will be less verbose and shouldn't try to double-ident
:    ahci0.0.  I'm hoping that is the cause of the forever-repeating
:    timeouts.

    I'm going to assume those last two tags=/f86= where actually from
    the other disk and you mis-typed them.

    If that's the case it might be an issue of the drive or the controller
    not being able to support SATA-300.  It may help if you post what the
    NATA driver reports for those attachments (set hint.ahic.disabled from
    the boot loader).

    I am also going to add a new kenv called hint.ahci.force150 which will
    force it to negotiate at a slower speed.  That's being committed as
    we speak.
