Win10 LTSB. 18.6.1, 8x Vega56.
It's not random, it's GPU 6 and GPU7 every time, and it doesn't show GPU6 and GPU7 at startup, it can be seen in the thread. Using -d 0,1,2,3,4,5,6,7, the problem remains
If you start with -d 2,3,4,5,6,7, then -d 2,3,4,5,6,7,0,1, what happens? I'm curious if it's always the last two cards in the provided device order that are failing or if it's always your GPU6/7 in the OpenCL enumeration...
