Well - if you are getting speed above 22MB/s you are definitely using
Andre's code for UDMA4 - the only problem is if you are stressing
your computer to hard you will get deadlock sooner or later -
for bp6 the safe mode seems to be UDMA3 - around 24MB/s (-X67)
(-X68 is UDMA4 - the mode you are using)
(For 2.4 kernels the default mode for IBM drives is now UDMA3)
