[fedora-arm] Pinebook Pro and reboot

So, I was able to install Fedora on the Pinebook Pro following the blog post https://nullr0ute.com/2021/05/fedora-on-the-pinebook-pro/ The only difference is that I was unable to boot the installer from an USB stick, and I used dd to copy the content of the SD card to eMMC. The only annoying problem that I'm facing is that I can't reboot the Pinebook. I can reboot, sure, indeed, connecting through the serial port, the system actually reboot, but the video becomes black with some horizontal lines [1]. Powering off the system, then on, the screen is ok. What could it be?
