1. Please describe the problem: amdgpu not correctly initialized with latest kernel (5.14.15-200) 2. What is the Version-Release number of the kernel: not working 5.14.15-20, works with previous versions 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : works with 5.14.14-200.fc34.x86_64 and previous kernels 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: workstation with A10 apu, 4k monitor and amdgpu. kernel started with: vmlinuz-5.14.14-200.fc34.x86_64 root=/dev/mapper/rootvg-rootlv ro rd.lvm.lv=rootvg/rootlv rhgb quiet radeon.cik_support=0 amdgpu.cik_support=1 amdgpu.bapm=1 amdgpu.dc=1 amdgpu=1 is required because I dont get a sceen in 4k without it. I debugged this years ago, always worked unitil today 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: didn't try 6. Are you running any modules that not shipped with directly Fedora's kernel?: nope 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag. please check differences: previuos kernel (dmesg|grep amdpgu) WORKING [ 0.000000] Command line: BOOT_IMAGE=(hd3,gpt2)/vmlinuz-5.14.14-200.fc34.x86_64 root=/dev/mapper/rootvg-rootlv ro rd.lvm.lv=rootvg/rootlv rhgb quiet radeon.cik_support=0 amdgpu.cik_support=1 amdgpu.bapm=1 amdgpu.dc=1 [ 0.203879] Kernel command line: BOOT_IMAGE=(hd3,gpt2)/vmlinuz-5.14.14-200.fc34.x86_64 root=/dev/mapper/rootvg-rootlv ro rd.lvm.lv=rootvg/rootlv rhgb quiet radeon.cik_support=0 amdgpu.cik_support=1 amdgpu.bapm=1 amdgpu.dc=1 [ 4.206856] [drm] amdgpu kernel modesetting enabled.

I dont get a screen but I can log remotely. If I remove kernel argument amdgpu.dc=1 with latest kernel the system does not boot (hang)
I'm not the first one to report this: https://www.reddit.com/r/archlinux/comments/qkoolz/linux_51415_breaks_display_modesetting_on_ryzen/
I don't have a way to remotely login to my laptop at the moment to see the exact location where it stopped, but I also run the amdgpu module and 5.14.15-200 boot halted at the point when LUKS would normally prompt me. Manually selecting 5.14.14-200 from the GRUB menu successfully booted. All devices in my household and for work use the amdgpu module, so I'd love to help debug this if there's anything I can do to help figure this out.
Fixed: IOMMU must be enabled in bios. The default value for my mb is disabled. Is it a feature or a bug?
I have experienced the same issue with kernel-5.14.16-201.fc34.x86_64, so not change yet at least for me. I have not checked my laptop's IOMMU option in the BIOS, nor do I even know if this option is exposed. Kernel version 5.14.14-200.fc34.x86_64 remains the most recent one to work without this issue. Another kernel upgrade, however, will cause this version to be wiped-out with default options of only preserving n-2 versions of the kernels.
