I suspect that the drive is simply choking on the barrier related cache 
flushing that we do - that seemed to be the MacOS error as well. The 
windows comment suggested that windows had an hba/driver bug (most 
likely unrelated to this).

If you want to avoid the issue until they fix the drive, you could run 
fast and dangerous (mount without barriers on) or slow and safe (disable 
the write cache).

This looks to me to be a drive firmware issue. I would wait until 
someone can test with their announced firmware upgrade before looking at 
the kernel :-)
