Cause:	A device interrupted which had a device address not in the
	range of one of the known devices.

Action:	If a new device has been added to the channel with this address,
	support should be added to PHYSA for the device.  Otherwise there
	is a hardware malfunction, and probably there is a bad bit on
	the channel somewhere: compare the device address to the known
	devices on that subchannel.

Data:	DEVADR - The device address
