	this message appears only once in the aha1542.c code, in the function
	aha_timeout().   stefan esser added to the ncr.c code to deal with
	time outs by extending the interval for command completion.  
	the timeout was extended from 4 to 1200 (which is 20 minutes, if 
	i remember correctly that the units are seconds.)

	the timeout is part of the struct scsi_xfer and is set in scsi_base.c
	BUT this is kermel code version dependent.  so what are you
	running?  


	this should go to the scsi mailing list, i am going to cc: it
	there and remove -hackers from the list
