>Description:
	The LaCie 160GB USB drive hangs reporting BBB timeouts.
>How-To-Repeat:
	Any substantial activity on the LaCie drive (fsck for example).
>Fix:

	The LaCie drive needs a quirk in scsi_da.c.  something like
	this will do:

	{
                /*
                 * LaCie 160GB USB drive
                 */
                {T_DIRECT, SIP_MEDIA_FIXED, "Maxtor*", "6Y160P0*", "*"},
                /*quirks*/ DA_Q_NO_6_BYTE|DA_Q_NO_SYNC_CACHE
        },

	I'm not quite sure whether the DA_Q_NO_SYNC_CACHE is actually
	necessary, though.
