What steps will reproduce the problem?
1. Ejected UBS HDD formated with zfs.
2. Inserted HDD again.
3. Kernel crashed.

Another crash, but this time I didn't do anything, just writing some files into 
my hdd.

Hmm, it looks like the drives disappear from the system without prior 
notification.
ZFS is designed to panic in that case, because there is no safe way to continue 
operation.
You must export a pool before physically pulling the drive in the pool.
I'll leave the report open for now, but I don't think this is a bug.

Thanks for your comment.
Today I had 3 the same crashes (as usual) and I didn't ejected my drive as I 
was in the middle of copying and downloading the data into my HDD.
I had 2 crashes when actually uncompressing the compressed file from the hard 
drive.
My HDD is: WD My Passport 1TB USB 1000GB (Model: WDBBEP0010BBK).
OS: 10.9

Let me know if you have any suggestion.

The crash happens all the time when restoring my laptop from sleep time and I'm 
simply re-connecting the HDD.

This is probably the duplicate of:
Issue 51:   USB not supported

Again, when connecting the USB drive:

I had this also happen to me. I have a macbook with two thunderbolt ports that 
I use to connect two separate volumes on separate disks to (via seagate 
thunderbolt adapters). I was copying files from one disk to another when I had 
the exact same panic happen.

I have something similar happening - thunderbolt disk with WD green 3tb drives. 
The mirrored pool works and stays mounted on an old PPC mac - albeit with 
performance issue.

I have tried mounting pool with one of the 2 disks (status degraded) and have 
the same issue - after perhaps 30 seconds the kernel panic occurs.

I have the crash logs and can reproduce at will if required.

Not performing any file operations, just post mounting the drive(s).

MacZFS has been discontinued.  Please switch to https://openzfsonosx.org/
