Additional Info: AMD Ryzen 5 3400G with AMDGPU -- 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 :04:00.0: amdgp : failed to write reg 28b4 wait reg 28c6 Jan 4 15:26:56 inspiron-3505 kernel: [ 54.189055] amdgpu :04:00.0: amdgp : failed to write reg 1a6f4 wait reg 1a706 Jan 4 15:27:16 inspiron-3505 kernel: [ 74.329264] amdgpu :04:00.0: amdgp : failed to write reg 28b4 wait reg 28c6 Jan 4 15:27:36 inspiron-3505 kernel: [ 94.337904] amdgpu :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.
