Assertion failures indicate bugs. You might try another version of the OS.
In general, they are easy to search for in the bugs database. A quick
search reveals
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6822816
but that doesn't look like it will help you. I suggest filing a new bug at
the very least.
I have redispatched 6822816, so it needs to be reevaluated since more
information is available now.

Running snv_114 on an X4100M2 connected to a 6140. Made a clone of a
snapshot a few days ago:
# zfs snapshot a...@b
# zfs clone a...@b tank/a
# zfs clone a...@b tank/b
The system started panicing after I tried:
# zfs snapshot tank/b...@backup
So, I destroyed tank/b:
# zfs destroy tank/b
then tried to destroy tank/a
# zfs destroy tank/a
Now, the system is in an endless panic loop, unable to import the pool
at system startup or with "zpool import". The panic dump is:
panic[cpu1]/thread=ffffff0010246c60: assertion failed: 0 ==
zap_remove_int(mos, ds_prev->ds_phys->ds_next_clones_obj, obj, tx)

We really need to import this pool. Is there a way around this? We do
have snv_114 source on the system if we need to make changes to
usr/src/uts/common/fs/zfs/dsl_dataset.c. It seems like the "zfs
destroy" transaction never completed and it is being replayed, causing
the panic. This cycle continues endlessly.
