This may be related to the fact that I was running two different AMD video cards, one with amdgpu and the other with radeon drivers. That is how they were automatically installed.
I have since moved one card over to a vfio driver for pci passthrough, so effectively it's not doing much with the kernel anymore, and the issue has gone away. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873548 Title: [amdgpu] hangs at shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1873548/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
