I have a 486/90 running NetBSD 1.2.  This system has been fairly 
 stable at the remote location, VA, until recently.  Now the folks
 over there are telling me that it crashes pretty regularly with the 
 following error.

	aha0: DMA beyond end of ISA  

 This occurs after running smooth for several hours but less than a 
 few days.  Any ideas?


Thanks, 
Aaron Williams
