Fedora doesn't include a spi Version, so I used spi firmware from Armbian late 2020, which is according to Arabian docu mainline U-Boot. And everything worked since then.
But when the kernel issue arises, the system is already running from NVMe device, isn't it?
Everything else is plain Fedora. I used arm-installer to copy everything to NVMe instead of SD.

It is the Rock Pi 4a (without wifi), Board revision 1.4 which is the first revision with a soldered SPI module.

I get after the update the same output as with the installation kernel. That is the EFI selection screen, the the display goes blank so some seconds, then the online message in the first line „BootingFedora …, then the display goes blank again for some seconds, and the output as I wrote in my previous mail. The keyboard is with both kernels not operational when the EDI screen is displayed.

I have different NVMes: Crucial, WD, transcend. The problem comes up with any of them.
I just installed the F36 distributable on another NVMe and updated just the kernel, with the same result, but a slightly different output:
Started plymouth-start.serie - Show Plymouth Boot Screen.
Started systemd-ask-passwouuuwsts to Plymouth Directory Watch
Readched target paths.target - Path Units.

I think I will install it again and exclude the kernel from update and see what happens.

After the Line Booting Fedora Linux, the display goes blank for some seconds (no sync according to the display LED) and said lines are displayed.

That's good, So it is hopefully „just" a problem with Rock Pi and not with a lot of other models, too.
