I confirm the same crash bug in Kernel versions:

4.4.0-66-generic
4.4.0-64-generic
4.4.0-21-generic

I could not test with latest upstream kernel because I needed ZFS (I looked into building it for latest upstream, but found no reasonable path).

I can also confirm the crash is related to a drive with bad sectors. In my case a Seagate 2TB
ata-ST2000DM001-1ER164_Z4Z55RQ2

Once I removed that drive, the crashing stopped.

If I booted with drive offline, and then added it to a booted system, it did not crash until I imported the ZFS pool.

I can try some simple tests with DD to confirm the crash in later or earlier kernels.
Since I do not want to break a now working system, any testing would be done booting a USB Flash image with only the failing drive connected to a sata_mv port.
