Unfortunately you haven't provided much in details regarding the 
hardware you are running as far as FreeBSD see's it.  I can confirm I 
have had many systems using m.2 for quite a while and have had zero 
issues.  Could you provide some of these details?

(assuming this is an NVMe device):
$ sudo nvmecontrol  devlist
$ sudo pciconf -lv nvme0

if your device isn't NVMe and is a sata device then this info may be 
helpful as well:
$ sudo camcontrol devlist

and your dmesg will also probably be helpful here as well.  I think 
getting at least this basic info will help determine where the issue is 
cropping up.
