Hmmph. The WRITE_SAME code, huh?
I know Nexenta's done a LOT of improvements on this in illumos-nexenta. It might be time to upstream some of what they've done. I know it's a moving target (COMSTAR is not a well-written subsystem), so it may take some unravelling.
I'm downloading the dump, in case the actual panic is more straightforward than most code in there. I worked on this a long time ago back when I was at Nexenta. It was provided to me by a contractor, and I had to bang it into shape for upstreaming. Clearly I missed something.
