Perhaps its not long enough in your new system. My other guess is that the bus settle delay isn't long enough. What's the value of SCSIDELAY in your kernel? Is DELAY() really so dependant on the CPU speed? Can we get a better DELAY() macro? > >Thanks, >-- >Bob Willcox >bob@luke.pmr.com >Austin, TX -- Justin T.
