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 Kernel Packages, which is subscribed to linux-hwe-5.13 in Ubuntu. https://bugs.launchpad.net/bugs/1956401 Title: amdgpu hangs for 90 seconds at a time Status in linux-hwe-5.13 package in Ubuntu: Confirmed Bug description: This does not occur with linux-image-5.13.0-22-generic, but does with linux-image-5.13.0-33-generic. On startup, I get about a 60 second hang, with the following in the kernel dmesg: Jan 4 15:26:36 inspiron-3505 kernel: [ 34.160572] amdgpu 0000:04:00.0: amdgp : failed to write reg 28b4 wait reg 28c6 Jan 4 15:26:56 inspiron-3505 kernel: [ 54.189055] amdgpu 0000:04:00.0: amdgp : failed to write reg 1a6f4 wait reg 1a706 Jan 4 15:27:16 inspiron-3505 kernel: [ 74.329264] amdgpu 0000:04:00.0: amdgp : failed to write reg 28b4 wait reg 28c6 Jan 4 15:27:36 inspiron-3505 kernel: [ 94.337904] amdgpu 0000:04:00.0: amdgp : failed to write reg 1a6f4 wait reg 1a706 I have the following GPU: 04:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

I get a similar hang if I start firefox (when it's probing OpenGL contexts), and even with glxgears and glxinfo. Seems like anything that'd kick on a OpenGL context does it. I had a freeze as well when I tried running firefox and glxgears both. Along with odd BUG: messages logged (I have some in the attached log.) I was running with "iommu=pt", but did try with this removed, still got the errors (I think amdgpu driver uses the IOMMU even when it's set to IOMMU=pt though.). See the attached log for some very odd "[Hardware Error]" messages that were logged on one test run. I think this was when I tried to run firestorm (second life viewer) -- that had a large pause then opened to a black window. Per Google, I see there was a bug like this that turned up in kernel 5.14.15 but fixed in 5.14.17.
