	I have probbly the same problem. From time to time I get
messages like the following:

sd0: not queued
sd0: not queuedswap_pager_clean: clean of page 1005000 failed
aha0: DMA beyond end of ISA
sd0: not queuedswap_pager_clean: clean of page 1009000 failed
aha0: DMA beyond end of ISA

swap_pager_clean: clean of page 1037000 failed
	
	And from time to time (about once every two days), hangs.
The machine says when booting:

	Does all of this says something to somebody????
