RX VEGA 56 - AMDRadeonAccelerator prodding blockFenceInterrupt

[leto1210]

Hello everyone,

I writing to you for a strange behaviour.

My Hackintosh is fully fonctionnal but I got a strange error with my Vega 56.

Each time I got a huge activity on my card with Blender Benchmark or Games like Minecraft ( ), I got a lot of errors and the program crash after fews minutes.

Have you got any ideas ?

Full description of my config is available on my github project ==> z390-Hack

Please find a copy of my config.plist and my EFI repo.

Thanks !

Following troubleshooting:

1. I have trying iMacPro1,1 profil and deactivating the iGPU ==> same behavior
2. Fallback to iMac19,2 and applying last MacOs update 10.14.6 ==> same behavior

1.
