The SHA was also given, and I didn't know what else you would need.
The openQA link was given to show the dmesg.

Yes, and I still say that, its just a boot test.

yes, something which has always worked in boot-testing LTS kernel or
mainline kernel.

I only found that the "WORKER_CLASS" has the name "qemu_rpi4", that is
a name which I choose to give as that worker laptop is connected to
rpi4 and also running qemu tests. If you want I can change the name of
the WORKER_CLASS. :)
iiuc, dmesg shows if its booting in a qemu or on a real hardware.

I have now ordered another rpi4 board and will create the image from
scratch and give you the steps.

I am not really sure why you are trying to figure out a random CI
system. I can reproduce the problem in our setup everytime I test with
that reverted commit and I have already said I am happy to test with a
debug patch or anything else.
