Boot stops at starting local on kernel 5.5.7

[Federile]

So the first time I booted with the new kernel it freezed with switching from VGA, so I found out the setting nomodeset and the booting arrived until the "Starting local" so here I was able to enter the tty and try to start the X server.
This returned me with no display found. I checked out the dmesg for errors and there received VGACON disables amdgpu kernel modsetting. Now even with the nomodesetting the booting stops even with other kernels, what should I do ?

On any vaguely modern system, using nomodeset is likely to cause more problems than it solves. You should use it only as a debugging step to validate that modesetting is responsible for a problem. Please describe more precisely where the boot halts, and how. Does the kernel panic? Are you stuck waiting for an initscript to complete? Which one? On what kernels have you observed the problem?

[Federile]

So if I don't use nomodeset than the boot freeze so I can't really see what is going on. It freezes when it switches from VGA to amdgpudrmfb, it doesn't say more than that

[Hu]

Is anything written to the log? How do you know that the system is frozen? On what kernels have you observed this to work? What was changed between the working and non-working kernel?

[Federile]

So for is not working I mean that the booting just freezez with having as last log "fb0: switching to amdgpudrmfb from EFI VGA", and then the machine is still going but it doesn't print anything. I experience this in the 5.5.7 kernel, after compiling the kernel for the first time, all the other kernels versions works until I don't put nomodeset, if I put nomodeset than 5.5.7 and 5.4.7 would block themselves as they are unable to boot lightdm or any graphical interface. In that case I'm still able to enter the tty and there running dmesg I receive the error: "VGACON disables amdgpu kernel modsetting"
