Well, after building the kernel with your patch, installing it and 
booting off of it, the system does not panic.

It reports this when I mount the filesystem:

    Solaris: WARNING: dva_get_dsize_sync(): bad DVA 131241:2147483648
    Solaris: WARNING: dva_get_dsize_sync(): bad DVA 131241:2147483648
    Solaris: WARNING: dva_get_dsize_sync(): bad DVA 131241:2147483648

Here is the results, I can now mount the file system!

    root at working-1:~ # zfs set canmount=on zroot/data/working
    root at working-1:~ # zfs mount zroot/data/working
