Created attachment 1781669 [details] F34 dmesg from first boot after installation 1. Please describe the problem: The display goes blank after panfrost/rockchipdrm module is loaded. This happens on all F34 DVD ISO images (Workstation and KDE). 2. What is the Version-Release number of the kernel: 5.11.12-300.fc34.aarch64 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 : Unknown. These are the F34 GA DVD ISO images. 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Write one of the images below on a USB stick and boot Pinebook Pro from it: https://download.fedoraproject.org/pub/fedora/linux/releases/34/Workstation/aarch64/iso/Fedora-Workstation-Live-aarch64-34-1.2.iso https://download.fedoraproject.org/pub/fedora-secondary/releases/34/Spins/aarch64/iso/Fedora-KDE-Live-aarch64-34-1.2.iso sudo dd if=./Fedora-KDE-Live-aarch64-34-1.2.iso status=progress bs=1M of=/dev/sde Flash U-Boot to SPI (https://nullr0ute.com/2021/05/fedora-on-the-pinebook-pro/), reboot and boot from USB at U-Boot prompt: => run bootcmd_usb0 After booting the kernel, some of the messages scroll quickly at the top of the screen and then it goes blank. I only get output on the serial console. 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``: Unknown, I haven't tried yet. 6. Are you running any modules that not shipped with directly Fedora's kernel?: No. 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.

FYI this is fixed by 5.12.5 that just hit updates-testing.
