:Strange, could you post a backtrace?
    That sort of error is virtually guarenteed to be due to the disk
    driver not reading the data or reading the wrong data.  It is exactly
    what happens to me when I mess up a block number translation in a
    driver, or if biodone() is called without properly setting b_resid.
    My money is on b_resid, b_flags, and/or b_error not being set properly
    on I/O completion.
Still, I have 3 running systems with NATA where this sort of thing 
doesn't show. I'll recheck the ad code just to be sure, but still some 
more info from the victims would be nice.
