I'm not entirely sure what is causing the problem with your system, but
hopefully we can narrow it down a bit.

There is a bug that came in with my SMR changes in revision 300207 that
broke the quirk functionality in the ada(4) driver.  I don't think that is
the problem you're seeing, though.

Can you try out this patch:

https://people.freebsd.org/~ken/cam_smr_ada_patch.20160523.1.txt

In /boot/loader.conf, put the following:

kern.cam.ada.0.quirks="0x04"
kern.cam.ada.1.quirks="0x04"

If you're able to boot with those quirk entries in the loader.conf, try
taking one of them out, and reboot.  If that works, try taking the other
one out and reboot.

What I'm trying to figure out here is where the problem lies:

1. The bug with the ada(4) driver (in where it loaded the quirks).
2. The extra probe steps in the ada(4) driver might be causing a problem
   with ada0 (Samsung drive).
3. The extra probe steps in the ada(4) driver might be causing a problem
   with ada1 (Seagate drive).
4. Something else.

So, if you can try the patch and try to eliminate a few possibilities, we
may be able to narrow it down.

Thanks,

Ken
