# Here is a log of an attempted boot with ATA_DEBUG defined.  It looks like

For what it's worth I get the same two lines:

	ata0: devices = 0x1
	ata1: devices = 0xc

So it found the master (the HD) on the first controller, but it
appears to find both a master and a slave on the second controller.
The problem is that the DVD-ROM doesn't appear to repsond correctly
to either of the attempts to determine which one it wants to be.

Just for grins I changed the ata_probe to ignore all but the first
controller and it is back to the ufs_dirbad panic. :(
