I've been having the suspend issue for the past week or so with the 5.13 kernels on an Atari VCS, which has a AMD Ryzen Embedded R1606G with Radeon Vega Gfx. Current kernel installed is 5.13.0-27-generic. I've also noticed that anything that tries to use Vulkan as a display driver segfaults. Upon bootup, dmesg has some bad looking errors in it: [ 2.772683] kfd kfd: amdgpu: error getting iommu info. is the iommu enabled? [ 2.772687] kfd kfd: amdgpu: Error initializing iommuv2 [ 2.772899] kfd kfd: amdgpu: device 1002:15d8 NOT added due to errors
FWIW, I have this setup cloned to an Intel laptop, and everything appears fine there. The 5.13 series even enabled my wireless card on that laptop, since that wireless card wasn't supported until 5.12 or later. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1956401 Title: amdgpu hangs for 90 seconds at a time in 5.13.0-23, but 5.13.0-22 works Status in linux package in Ubuntu: Fix Released Status in linux source package in Impish: Fix Released Status in linux source package in Jammy: Fix Released Bug description: SRU Justification Impact: This does not occur with linux-image-5.13.0-22-generic, but does with linux-image-5.13.0-23-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. [AMD/ATI] Picass o (rev c2) (prog-if 00 [VGA controller]) 04:00.0 0300: 1002:15d8 (rev c2) (This is a Ryzen 5 3450U CPU with Radeon Vega Mobile.) 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. See https://gitlab.freedesktop.org/drm/amd/-/issues/1770 Thanks! --Henry Fix: upstream commit afd18180c070 ("drm/amdkfd: fix boot failure when iommu is disabled in Picasso.") Patch was included in the Impish kernel in -proposed (5.13.0.24.24) from an upstream patch set. multiple confirmations the problem is resolved with the kernel in -proposed.
