That's a BIOS bug with VCN not a GPU F/W bug. We can reproduce it on the same BIOS as you, and updating to a newer BIOS it goes away.
You can workaround it by masking the VCN IP block like this: amdgpu.ip_block_mask=0xfffffcff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2068001 Title: Add support for DCN 3.5.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/2068001/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
