Okay. Just so we can narrow it down a little more, can you try this:
First, let's try getting an ATA Log directory using the PIO version of the
camcontrol cmd ada0 -v -a "2f 0 0 0 0 0 0 0 0 0 1 0" -i 512 - |hd
If that works (you should get hexdump output), try the DMA version of the
camcontrol cmd ada0 -v -d -a "47 0 0 0 0 0 0 0 0 0 1 0" -i 512 - |hd
My hope is that we can confirm whether or not this is what is causing the
Samsung drive to have issues. It is certainly possible to put in a quirk,
but I'd rather not make it unnecessarily broad.
