I'm assuming the 5.14.15 or 5.14.16 amdgpu and amdkfd has been backported to the 5.13 Ubuntu kernel. Here's the patch in 5.14.17 that specifically addresses this. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.14.17&id=7883e13c249461877ea3be7b24a5935fc8946e46
The other amd-related patches for 5.14.17 largely appear to be fixes to DCN3.1 support (newest GPU models from last 6 months or so.) This is a fairly serious regression for those affected (I may have only gotten to a desktop because I"m using Gnome Flashback so no compositor trying to exercise the 3D hardware for desktop use. I've simply gone back to 5.13.0-22 for now.) If the plan is to ship a quick update, I could see just patching in that one patch; if it'll be fixed in 5.13.0-23 at a usual schedule I could see incorporating all of them to benefit DCN 3.1 users. Not to dissemble, but kudos to the open source GPU driver developers, the Intel support's amazing (it's amusing on my friends Sandybridge, that he can run DX11 games in steam through Proton that it would not be able to run in Windows since Intel never shipped DX11 drivers for it...), and amdgpu has run every game I've thrown at it so far, generally at very good frame rates. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1956401 Title: amdgpu hangs for 90 seconds at a time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.13/+bug/1956401/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
