XFS has a different issue with barriers that has been recently fixed.

I am just going based on what I read at the Seagate customer site - it 
looks like the hang was during the processing of the ATA_CACHE_FLUSH_EXT 

New drives are routinely buggy to some degree, especially ones that jump 
up in capacity :-)  Seagate has a well earned reputation for quality and 
I will be surprised if they don't fix this issue soon,
