I updated to the latest HiveOs image and my Vega cards had permission errors and caused the system to restart in a loop. The version is 5.15.0-hiveos #96 with AMD drivers A21.50.2 (5.18.2301). My other AMD cards work fine: 570, 580, 5700, and 5700xt with this latest image.
I have reverted the one rig back to the previous version that works, the version prior to the latest release.
