kernel-6.3.0-0.rc1.20230309git6a98c9cae232.18.fc39.x86_64 has this resume problem. kernel-6.3.0-0.rc0.20230227gitf3a2439f20d9.9.fc39.x86_64 is the first Rawhide kernel without the black screen during boot problem https://gitlab.freedesktop.org/drm/amd/-/issues/2319 and it has this failure to resume problem. The previous build kernel-6.3.0-0.rc0.20230223gita5c95ca18a98.4.fc39.x86_64 had the black screen during boot I reported this problem to the IOMMU subsystem mailing list at https://lore.kernel.org/all/4a3b225c-2ffd-e758-4de1-447375e34cad@bell.net/T/#u Vasant Hegde and Felix Kuehling explained the details of the problem in amdgpu there. Thorsten Leemhuis added the problem to regzbot. https://lore.kernel.org/all/4a3b225c-2ffd-e758-4de1-447375e34cad@bell.net/T/#m52dfb8f457727ce725aad66e5e7db4e8afa46fad https://linux-regtracking.leemhuis.info/regzbot/regression/217170/ I built 6.3-rc2 after applying Felix's patch at https://lore.kernel.org/stable/20230314175359.1747662-1-Felix.Kuehling@amd.com/ amdgpu resumed normally 5/5 times with 6.3-rc2 + the patch. Felix's patch fixed the problem. Thanks. Felix Kuehling's patch to fix this problem was pulled into the mainline branch on 2023-3-17 and is in 6.3-rc3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=master&id=f3921a9a641483784448fb982b2eb738b383d9b9 6.3.0-0.rc3.30.fc39 didn't have this problem when resuming a few times. Felix's patch is queued for the 6.2 branch at https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/commit/?id=d68ccb83abd757877de8c7f344fa43c05b81760f |
