So the conclusion is that your driver and/or hardware corrupts data when
you set MAX_XFER_SECTORS too high. I can't help you anymore with this,
you should be in the best position to debug the driver and/or hardware
:-)

It could be that the higher setting just exposes another transfer
setting bug, like maximum number of segments or segment size, etc.
