Okay, I've got a basic idea of what may be going on.  The resets that are
getting sent are triggering another probe, which then triggers a reset,
which triggers a probe...and so on.

So here is another patch that should work for you:

https://people.freebsd.org/~ken/cam_smr_ada_patch.20160524.2.txt

I have commented out the quirk for this drive, and the driver will now only
start the SMR probe on drives that claim to be SMR-capable.  So, for the
vast majority of drives out there right now, it won't even start the extra
probe steps.
