Pretty well.   As I mentioned, pressing the power button caused a
'powerdown initiated on /dev/console' or similar (from memory) but
shutdown did not proceed.  I did have a ssh session open but although I
could type into it, nothing happened after I pressed Enter.  Nothing
that required disk activity would work.

Yes, OmniOS v11 r151013

Do you mean a snapshot to the filesystem on which it hung?  It's 69.5
GiB.  In any case, as I mentioned, I could copy it once I was back on
r151013, so I don't think there's anything unreadable there.  Maybe
some unsupported feature ?
