My SN550 was brought into a pretty bad state that it triggers AER flood on a
Linux system and the BIOS was also affected that I can't even enter the BIOS
setup page.

As a desperate last resort, I move the disk into another machine (a NUC box).
Magically the NUC box recognized the broken disk without problem, and booted
just fine (Actually I lied, it landed on a prompt saying it's a FreeNAS data
disk, which at least proves the disk can read just fine).

Now after I moved it back to my home server box, the disk backs to live once
again. I'm able to scrub the ZFS pool on this disk and find no data error at
all.

This time, I didn't run into any issue with APST enabled or disabled, which is
really surprising.

Let me switch back to the offending FreeNAS system to see how it behaves this
time. Is this really a physical connection problem? How could it be -- I didn't
use any adapter cable but directly hook it onto the M.2 slot on my motherboard.
