You might look for a BIOS update.

I am just beginning to learn about all of this M.2 stuff.

But here is my suspicion at this point.  PCI-E lane complication.

See: https://www.pugetsystems.com/labs/articles/Overview-of-M-2-SSDs-586/  And scroll down to "PCI-E lane complications".

can give me some guidance.)

  once upon a time, i whined pathetically about problems sticking a
samsung 950 PRO M.2 SSD into my ASUS G752VL-DH71 gaming laptop
currently running fedora:

  http://osdir.com/ml/fedora-users/2016-07/msg00410.html

eventually, i tripped over this ASUS forum page:

  https://rog.asus.com/forum/archive/index.php/t-79590.html

where one gets the distinct impression that that particular samsung
SSD is not compatible with my laptop, but one is assured that what
does work is the samsung SM951, which i picked up, with still no luck,
still getting early error message:

  ata1.00: failed to enable AA (error_mask=0x4)
  ... etc etc ...

this is the SSD:

https://www.amazon.com/Samsung-SM951-512GB-NVMe-MZVPV512HDGL-00000/dp/B015CWR4M2

and i'm running out of ideas; do i need to roll my own kernel to add
support for this thing? i would have thought that if i don't have
support, the SSD would just be ignored, and not choke the system.

  i'm about to do more testing this weekend, but i sure would like
some advice.
