That is weird but doesn't seem to be a libata problem.  Can you describe 
in more detail - what method did you use to copy the file?  How low is 
low transfer rate and how high does it get?  What's the result of hdparm 
-tT?  Also, can you try to transfer from /dev/zero and see what happens?

And what other strange behaviors do you see?

I think it might be a scheduler issue or some weird IRQ routing problem 
although not very likely as IRQs are not shared.

I'm leaving full dmesg for lkml readers.
