Could I have you try this patch and see if that fixes things. The args=20
to busdma is not really correct as is. However if this still doesn't=20
work, either busdma is at fault for not giving us what we ask for or I=20
dont have the correct info on DMA restrictions on the sparc....
Maybe you could instument that fixup loop, if it still fails, so we=20
could tell what sizes etc gets delivered from busdma ?
