Hi. Today I experienced a random crash in my MacBook Pro TB 15" 2016 BTO  running macOS High Sierra 10.13.6.

My setup is a MacBook Pro TB 15" 2016 BTO (max specs CPU) hooked up to a Mantiz Venus with  a Sapphire Nitro+ RX Vega 56 graphics card to the left side of the machine
I have connected two Samsung 4k 28" displays via DisplayPort.

Also I have a Thunderbolt 3 OWC dock connected also in the left side in order to have Ethernet, Firewire (I have 3 legacy Lacie 2Big Quadra, and firewire audio cards) and USB 3.1

Today´s scenario: 

I was using the laptop in clamshell mode. I was not running nothing intensive. Just doing a TM backup, downloading files from a FTP site to an external SSD drive, running Ableton Live with iTunes using an external audio card with a MIDI keyboard. So, no intensive nor demanding apps. 

Out of the blue, the displays went black, I opened the lid of the MacBook Pro and get a kernel panic. I didn´t saved the report, but it says something related to the AMD drivers and such.

Anybody has experienced similar issues?

Ps: I also have a nTB MacBook Pro baseline (128 GB SSD, 8GB RAM) running Bootcamp, and I have been running 3D Mark stress tests like TimeSpy Extreme, FireStrike without any issues (despite of having my Sapphire Nitro+ overclocked to 1650 Mhz aprox.) I´m runnning the latest AMD drivers in Windows 10 64 bit.

I guess it´s an issue with High Sierra. What a crappy release...

Never happened here, just rarely you can get a kernel panic and it could be easily software related (os, drivers or some software playing dirty). If it happened one time don't worry.

I'm positive that it has to do with AMD drivers in macOS High Sierra and software related. What a load of crap!

Just to add details: It happened on the same machine, while doing a TM backup and using FileZilla to copy files to an external SSD disk. Both are connected trough a OWC Thunderbolt 3 Dock. Suddenly, out of the blue, both displays go off, I open the lid of the MBP and I get the KP.

Last time, I had to resume the TM backup, and it did two deep transversal scans, and then two TM backups to different disks, while running also FileZilla. The machine ran smoothly for 8 hours with the same behaviour without any KP. 

I higly doubt is a GPU issue. I’ ve already have run like dozens of 3D mark, Unigine Superposition stresst tests (more the 20 min.)  in another MBP nTB using Bootcamp and have zero issues. Also using macOS with that machine and zero issues. 

I honestly have not been able to replicate the KP. I don’t have a clue what it might be the issue...
