I bought a '''2015 MP Pro''' in August of 2018, and  immediately replaced the 128GB drive with  '''1.0TB OWC Aura Pro X'''   (I could not find a new 2015 MP Pro with a larger drive''')'''

Currently on Mojave (10.14.6)

I have same issue:  suddenly  the computer slows down a lot, then the screen starts to flicker, getting worse and worse, shut down takes a very long time.

It had been happening every 4-6 weeks, but it happened  3 times in past 4 days.

All of the panic logs show something like as shown below, with  '''IONVMeController''' mentioned.

Way back I contacted OWC and they sent me a new drive which I replaced.  It did not fix it, but I had been living with the “every 4-6 weeks” crash situation.

I had P'''ower Nap''' turned off.  I just now turned off  '''wake for network access'''.  I have not yet done this:  disabled standby from the terminal ("'''sudo pmset standby 0'''").  Headed to Genius Bar today and will see what they say.

I also freed up room on the drive, it had  30GB free now it has 200GB free .

I do not have drive encryption on, thinking that might make it worse and originally thought that might be part of the problem.

Typical panic report:
