@Feartech Thanks for that. I think my problem is a little different. Sorry I jumped in the wrong reply.
I have a working Mojave based on @kpg forum. I'm trying to update to 10.15.3 (on another 500gb 970 Evo) because I bought a 5700XT Saphire and I would like some h264 acceleration that performs better than Vega64 and use that as the main graphic card.
I managed to install Catalina but I'm currently getting either freezes or restarts 3-5 minutes after the boot. Please find attached my EFI and the kernel panic log after the restart. Please let me know if you have any thoughts. I haven't implemented yet the TB hotplug either. Please let me know if I'm missing something or have redundant stuff.
Here are my specs:
CPU: i9 7980XE MB: WS-X299-SAGE (base, not 10G)
GPU: 5700XT Sapphire & Vega 64 (Sapphire)
RAM: Corsair CMW128GX4M8C3200C16 RGB Pro 128GB (8 x 16GB) DDR4 3200 MHz C16 XMP
TB: GC-TITAN RIDGE NVME: 2X 500GB Evo 970 (1x for win 10, 1X for mac)
1x Blackmagic Mini 4k (HD &SDI)
6x 4TB HGTS (20Tb Raid)
1x Solarflare SFN5122F Dual-Port 10GbE SFP+
2x 27 Inch Apple Cinema Displays (mini display adapted to DP)
1x HDMI 27 Inch Sony for monitoring
