:I'm having a really hard time booting one of my machines.  It keeps
:getting stuck at:

:Waiting 2 seconds for SCSI devices to settle

:I'm able to break to debugger.  Here's what a ps looks like:

    One of the CAM devices is not returning from its XPT_BUS_SCAN
    action.

    You have to find out which one.

    We have to figure out which SCSI device is having the problem.  Any
    AHCI or USB stuff plugged in?  Or is the only CAM bus from the AIC
    driver?
