 This looks very much like the problem I've seen on Linux machines.
 The 'new' aic7xxx driver would negotiate lower speed than 'old'
 (aic7xxx_old) driver.  Newer driver reads SEEPROM and per-target speed
 settings stored there.  In my case, SEEPROM settings forced all targets
 to negotiate 10MB/s speed, while Adaptec BIOS displayed "40MB/s" as
 current setting.  The fix was to change all speed settings to something
 else, save them, and change them again to desired speed.
