Error with CMD 649 ATA100 controller while copying files over NFS on 4.11-Stable

I switched one hard drive to a CMD 649 ATA100 controller last summer, and I've 
had some trouble with it on 4.11-Stable. When I copy a large volume of files 
over NFS (800 Megabytes, lets say) the add on controller will stop 
recognizing my hard drive. This time the files were not being copied off a 
drive handled by this controller. 

Any ideas? This only occurs when copying files over nfs, and it will happen 
even when I am not copying anything involving the drive on the controller. 
I've tried "atacontrol reinit 2" and it won't re-recognize the hard drive 
(ad5s4f).  I have absolutely zero problems when I am not using NFS, 
especially zero problems with make worlds or building large ports on this 
hard drive in question.

Here is the dmesg I see after the hard drive is unrecognized by the ata
