Okay, I've got a basic idea of what may be going on. The resets that are

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.
It fixes this issue. I was able to boot with your latest patch.
Great! I'll check it in with that fix as well as a quirk entry. That way,
if we have other reasons later on to issue a read log, we'll know that
it doesn't work for those drives.
Might be worth seeing if smartmontools can read the log from that drive
before committing the quirk as a double check.
Regards
Steve
