     What version of Xen and the kernel are you running?  This bug was 
supposedly fixed in April:
http://lists.xensource.com/archives/html/xen-changelog/2008-04/msg00008.html

... but a similar (or identical) one appears to still have "NEW" status, 
posted on April 25th.

     Regardless of how you set swiotlb, under high I/O load, this bug 
has the potential to completely eat your storage array (I found out the 
hard way).
     As far as I know, it only seems to affect the 3Ware cards on 
64-bit systems, running a 64-bit kernel.
     3Ware's knowledge base says this about it:
